Abstract
An apparatus comprising a first circuit, a second circuit, and a third circuit. The first circuit may be configured to generate a first control voltage and a second control voltage. The second circuit may be configured to generate a bias signal in response to the first control voltage and the second control voltage. The third circuit may be configured to generate a filtered signal in response to the bias signal. The filtered signal may be added to the first control voltage and the second control voltage to provide AC noise suppression when generating the bias signal.
