Abstract
An apparatus comprising an analog circuit, a passive circuit and a first circuit. The analog circuit may be configured to vary a voltage of an output signal in response to a first signal. The passive circuit may be configured to further vary the voltage. The first circuit may be configured to further vary the voltage. The first circuit generally comprises a parasitic capacitance. The passive circuit and the first circuit are generally coupled in series.
