ABSTRACT:
A packet-based wireless transceiver that transmits and receives data packets comprises a receiver including a mixer that converts signal frequencies and a baseband circuit that communicates with the mixer and that includes an amplifier. A receiver voltage offset calibration circuit adjusts a receiver voltage offset at the baseband circuit at times synchronized with the data packets and includes a calibration signal generator that outputs calibration signals to first and second inputs of the baseband circuit and a calibration adjustment circuit that communicates with the calibration signal generator and that adjusts the calibration signal to reduce the voltage offset based on an output of the amplifier.
