Abstract: A wideband power detector (peak or RMS) is placed in a base-band portion of a receiver chain implemented with a current mode RF front end. A differential transimpedance amplifier (TIA) includes a current sense circuit that replicates the input currents to the TIA as current sense output voltages without the current sense output voltages being affected by the filter characteristics of the TIA.

Abstract: A wireless communications device includes a receiver having a phase detector configured to extract frequency offset and provide a corresponding error signal generated based on a baseband version of a received radio frequency signal and an expected transmitted data signal. The receiver has a phase-locked loop configured to generate an error correction signal based on a phase of the error signal and a predicted instantaneous phase of the error signal. The receiver has a correction circuit configured to provide a corrected baseband version of the received radio frequency signal based on the baseband version of the received radio frequency signal and the error correction signal. The receiver may have a re-encoding-based processing circuit configured to provide the expected transmitted data signal based on a preliminarily decoded symbol.
