This project aims at addressing the increasing demand for low-power and low-cost radio data links. We are seeing an exponential growth in the number of devices requiring short-range wireless connectivity where the energy budget is extremely restricted. In this context, a reduction in complexity is the most direct way to achieve power and cost reduction. Thus, the superregenerative (SR) receiver, with an intrinsically simple architecture, is a feasible choice that must be taken into account in different applications. In this project, we will first optimize for new applications: a) A prototype for M-PSK modulations will be developed. b) The ability to detect phase modulations on orthogonal frequencies will be investigated. This is the principle of what may be true OFDM. c) Certain SR variants exhibit an excellent time resolution. The application of this feature to radar and positioning problems will be investigated. d) Due to the availability of a front-end that behaves as a flip-flop, the feasibility of an all-digital receiver will be investigated. In this project we will also implement the CMOS integration of some SR designs. Finally, we aim at designing a SR transceiver accessible through an IEEE 802.16.4 interface, allowing the SR transceiver to coexist with sensor networks based on conventional transceivers.
