A receiver architecture suitable for coexistence applications is presented. The receiver features an auxiliary path to deflect blockers away from the main receiver without disturbing the desired received signal. The sub-2-dB noise-figure ( NF) receiver addresses the coexistence blocking issues without compromising the performance, achieving comparable NF and blocker tolerance to the state-of-the-art. Implemented in 40 nm CMOS, the entire receiver including the VCO and synthesizer drains 10 mA of battery current.
