Abstract
An integrated circuit includes a plurality of signal inputs, a receiver, calibration circuitry, and input switch circuitry. The receiver includes differential input terminals. The calibration circuitry is configured to calibrate an input offset between the differential input terminals of the receiver in response to the integrated circuit being placed in a calibration mode. The input switch circuitry is configured to switch electrical connections between the plurality of signal inputs and the differential input terminals of the receiver in response to the integrated circuit being placed in a mode different from the calibration mode. The input switch circuitry is further configured to electrically disconnect the plurality of signal inputs from the differential input terminals of the receiver in response to the integrated circuit being placed in the calibration mode.
