A Wideband FM Demodulator for a Low-Complexity FM-UWB Receiver

摘要

A wideband FM demodulator circuit for a low-complexity UWB communications system based upon double FM techniques is presented. The receiver demodulates the FM-UWB signal without frequency translation. The FM demodulator presented here covers the Low Band (3.1 - 5 GHz) and consumes 10 mW. The 0.72mm{sup}2 demodulator IC is implemented in 0.18 μm Si-Ge BiCMOS technology.
