Low power super-regenerative Impulse-FM-UWB transceiver for WBAN

Abstract

This paper presents a low power super-regenerative Impulse-FM-UWB transceiver architecture for wireless body area networks. The design architecture consists of two different colpitts oscillators tuned at 3.5GHz and 4GHz. 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 0.18µm CMOS technology. The data exchange rate of 2Mbps is achieved for detecting −95dBm signals with the power consumption of 400µW.
