Abstract:
An apparatus includes an amplifier, an input port, a first modulator circuit connected to the input port, and a correction circuit. The correction circuit is configured to determine a common mode voltage of the input port and receive a first clock signal. The correction circuit is further configured to manipulate, based at least in part upon the common mode voltage of the input port, the first clock signal to generate a second clock signal. The second clock signal is produced for the first modulator circuit. The correction circuit is further configured to determine whether the second clock signal is out of phase with a third clock signal, and, based upon a determination that the second clock signal is out of phase with the third clock signal, reset the second clock signal.
