A Wideband Receiver With Resonant Multi-Phase LO and Current Reuse Harmonic Rejection Baseband

In this work we present an architecture for a low power SDR which draws on techniques from both narrowband low power radios and recent work in SDRs. The receiver consists of a wide tuning-range passive mixer, driven with resonant non-overlapping LO drive combined with a noise-power optimized multi-path baseband amplifier. LO generation circuitry drives the… CONTINUE READING
