An on-chip AC coupled receiver with offset calibration. The receiver includes AC coupling circuitry to couple a differential input signal into a coupled differential signal having a first signal and a second signal. The receiver includes a first comparator to generate a first error signal indicative of whether a first reference signal is greater or smaller than a signal derived from the coupled differential signal. The receiver includes a second comparator to generate a second error signal indicative of whether a second reference signal is greater or smaller than the signal derived from the coupled differential signal. The receiver further includes feedback circuitry to adjust a voltage offset between the first signal and the second signal of the coupled differential signal based on the first error signal and the second error signal.
