We present a wide tuning range passive mixer-first receiver with resonant non-overlapping LO drive and noise-power optimized multi-path baseband amplifier. The receiver consumes 10-12mW (including VCOs, pulse generation and baseband) over a frequency range of 0.7-3.2GHz with a 1.3V supply. An LO generation architecture generates a 12.5% duty cycle resonant clock from standard complementary LC-tank VCOs. A capacitor sharing technique on the baseband side of the mixer doubles the RX frequency range of the 8-phase clock, achieving a NF as low as 7dB. The 1.8mW low noise baseband amplifier reuses the bias current of its four input channels while rejecting the 3rd/5th harmonics by >;34dB.
