Abstract :
A 4-4.5 GHz receiver front-end consisting of a 35 dB voltage gain regenerative amplifier, ultra-narrowband RF filter and an envelope detector demodulator for FM-UWB communication is described in this paper. Implemented in 65 nm CMOS, the measured receiver sensitivity is -83 dBm at 100 kbps data rate with 15 dB output SNR (10-6 BER). The 0.3 mm2 test chip includes a 50 Ohm buffer amplifier to facilitate testing and consumes 2.2 mW (excluding buffer) from a 1 V supply.
