Low power self-quenched super-regenerative impulse-FM-UWB transceiver for WBAN

This paper presents a low power self quenched super-regenerative Impulse-FM-UWB transceiver architecture for wireless body area networks. The design architecture consists of two different colpitts oscillators tuned at 3.5 GHz and 4 GHz. The external PCB loop antenna is incorporated into these oscillators as an inductive element to achieve high sensitivity and selectivity. These oscillators transmit impulses of FM-UWB signals in switched OOK mode and receive in super-regenerative mode. The design concept is simulated in 0.18 um CMOS technology. The exchange rate up to 2 Mbps is achieved for detecting -95 dBm signals with the power consumption of 500 uW.
