Common wisdom holds that it is dangerous to predict the future beforehand, and in this case common wisdom might actually be right. It might be a lot easier to envision and create (or at least enable) a desirable future. In this presentation, such a desirable future will be presented from a wireless perspective, as well as the required research to enable such a future. The role of the Centre for Wireless Technology Eindhoven (CWTe), its research programs and way of working will be presented within this context.

There is increasing awareness that sustainability requires sophisticated solutions in every domain of our lives. In many, if not all, cases sophisticated electronic functions will be required.
Whereas Moore’s law has enabled the digital society in the eighties and nineties, we are now entering an era whereby versatility of process and design technologies, in combination with a digital backbone is likely to change the landscape around us. In my company we call this the domain of High Performance Mixed Signal.
It appears to me that in the past, in our part of the world we have made significant contributions and have established a very well respected strength in this domain: both at academic level as well as in the industry.
Yet, there is no evidence of a structure in which we actively strengthen our combined expertise in this field, to the benefit of all participants, and to the longevity of the activity in this part of the world. My plea will be to change this.

The global challenges we face in energy, personal security, mobility and personal healthcare will drive the demand for semiconductor solutions that interface and interact even stronger than today with the different analog physical domains of the outside world. Those interfaces will be implemented in mixed-signal technologies and determine more and more the value of the overall semiconductor function.
One class of these interface functions will clearly be wireless transceivers for data communication and user interfaces.
Our local industry and academia have a great opportunity to jointly address the overall design challenges for these new wireless technologies at system level. Our combined know-how spans the full competence range from process and assembly technologies, antenna, RF, baseband and MAC design and with combined efforts we can ensure an effective and efficient open-innovation approach to sustain our global position in this field.

Wireless communication is becoming pervasive. With the explosive growth in available wireless standards, next generation wireless transceivers are required to have multi-mode capabilities in order to meet cost, size and time-to-market demands.
Multi-mode transceivers suffer from co-existence problems that result in reduced performance when more than one transmitter and/or receiver are active at the same time. Especially when a receiver is trying to receive a weak signal and at the same time at least one other transmitter is active, this can result in high linearity requirements to prevent desensitization through blocking. The 1-dB compression point and intermodulation intercept points for multi-mode transceiver combinations that are expected to be needed in the foreseeable future can be as much as 20dB higher than in current single-mode radios. Obviously, increasing power dissipation of a transceiver IC - via classical scaling - by a factor of 100 is not acceptable. Therefore, another solution is required.
This project aims at a major reduction of power dissipation through such an optimization across the RF/baseband border line. In particular, RF circuits will be modified for reduced power at the cost of increased tolerances and distortions. Concurrently, these tolerances and distortions will be compensated for, partly in RF (through calibration and/or adaptation) and partly in baseband (through digital algorithms). Besides reduced power dissipation, such a joint design approach is expected to yield further benefits, such as smaller RF circuit size, and hence cost. Techniques developed in the project can also be applied to other low-power and high performance receivers.
Erwin Janssen was born in Deurne, the Netherlands, on July 20 1982. He received the bachelor degree from Fontys Hogescholen in 2004, and the master degree from Eindhoven University of Technology in 2008, both in electrical engineering.
Currently he is working towards the Ph.D. degree at Eindhoven University of Technology. His main research interests are concerned with the digital compensation of nonlinear distortion in RF receivers.
Recently, there has been much interest in the design of wireless sensor networks, which are now being applied in many industrial and civilian areas such as industrial process monitoring and control, healthcare, home automation, etc. In most applications, wireless sensor networks work autonomously and are constrained by power consumptions. Consequently, the design of power-efficient communications are highly required for sensor networks. In order to develop wireless low-power technologies, a collaboration project is being carried out by CTWe and Holst Centre for maximizing sensor networks life span. The project is divided into two parts. One part mainly focuses on the ultra low-power radio receiver design to push the limit of RF front-end’s power consumption while the other part concentrates on the signal processing for enhancing the reliability of wireless links. In this presentation, we will show the current achievement of the project. The designed low-power receiver and the investigated channel coding schemes will be presented.

Future communication needs in Europe require increased efficiency and energy savings in applications such as cellular handsets, base stations, and mobile satellite communications. This is covered in the European PANAMA project (Power Amplifiers aNd Antennas for Mobile Applications). The role of the CWTe in PANAMA will be covered in this presentation. First, a general overview will be given of the project goal, its social and economical relevance, and the involved partners and participants (both from industry and academia). Next, a more detailed description of the TU/e contribution will be given, based on ongoing work in three sub-projects.
Rob M.C. Mestrom (1981) received his MSc degree (cum laude) from the Department of Mechanical Engineering at Eindhoven University of Technology in 2005. In 2009, he received the PhD degree from Eindhoven University of Technology. The topic of his PhD was first-principles-based multiphysics modeling and nonlinear dynamics in MEMS resonators. His research interests include modeling, nonlinear dynamics and control of (RF) MEMS.

His research is within the European PANAMA project and deals on RF MEMS switches, filters and phase shifters and their application to base station transceivers.
With rapid development of the wireless technology, low-power and short-range communications gain momentum and become increasingly important. When the market goes increasingly close to saturate and the technology becomes much more mature, a new demand on higher throughput pushes the wireless communication going further to the high-data-rate direction.
Along with the progress, however, both the wireless protocols and the physical systems and devices start to become complicated. Due to the technology limit, the power consumption of the devices, especially of the RF front-ends increase significantly. The power problem causes a dilemma that these high-data-rate wireless interfaces are hard to be integrated in the portable devices which are normally battery-powered.
Based on the challenge encountered, we propose the novel wireless wire communication solution. Instead of using the conventional communication method, a 60 GHz beamsteering directional communication is chosen, which confines the RF power within a narrow beam and increase the antenna EIRP gain by a factor of N2 in both transmitter and receiver (N is the antenna number). Since extra gain is obtained from the antenna beamsteering, less front-end gain is required, which in turn reduces the power consumption of the front-end. Besides, an ultra-low power duty-cycled wake-up receiver is added to listen to the channel, which is based on the injection locking approach. The main radio is switched on by the wake-up receiver only when a task is detected. Our entire system consumes less than 30 μW average power consumption with 1-Gbps data rate and 5-meter communication range in the normal WPAN scenario. This power level fits the battery-based wireless applications quite well. The physical system is implemented in standard TSMC 65-nm technology without any off-chip device, and thus it is low-cost for mass production.
