ABSTRACT:
A direct current (DC) offset correction loop (200) for determining the required amount of DC offset to an analog input signal includes a digital integrator (211) for measuring the amount of DC offset present at the final output of a forward signal path and a hold circuit (213) for controlling the digital integrator (213). The DC offset correction loop (200) provides a constant amount of DC offset correction to the analog input signal.
