SYSTEM AND METHOD FOR CALIBRATION OF MULTI-CHANNEL TRANSCEIVERS

Last updated:

Abstract:

A system for calibration of a multi-channel transceiver includes a plurality of voltage regulator circuits, wherein each circuit is configured to produce a voltage for circuitry of one channel of a multi-channel transceiver. The system also includes an analog multiplexer circuit configured to selectively route the output of one of the plurality of voltage regulator circuits to a single comparison circuit. The single comparison circuit is configured to compare an output of one of the plurality of voltage regulator circuits to a target reference voltage and produce an error signal representing a difference between the output of one of the plurality of voltage regulators and the target reference voltage. The system further includes a processor configured to accept the error signal and produce a feedback signal for the one of the plurality of voltage regulator circuits. The feedback signal is operable to adjust the voltage to minimize the difference.
