Abstract:A low-power regenerative FM-UWB receiver with wideband signal reception and linear FM-AM conversion is implemented in 65nm CMOS for short-range communication systems. Different from the conventional regenerative FM-UWB receiver having the narrowband LNA, the proposed receiver employs a vvideband LNA and dual bandpass filters (BPFs) to improve FSK demodulation with a relaxed Q requirement of the BPF. A 3.5-46Hz FM-UWB receiver consisting of a stacked LNA, dual BPFs, two envelop detectors and a subtractor successfully performs FM demodulation through wireless transmission from a 100kb/s FM-UWB t
