Abstract
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.
