Abstract:
This letter presents a 2.8-GHz low-power CMOS low-noise amplifier (LNA) with an embedded self-mixing power detector (PD) for low-overhead RF power monitoring. The detector reuses two existing LNA node voltages as the signal and local oscillator (LO) inputs for direct downconversion mixing, which avoids a dedicated LO generator, coupler, or …
