ABSTRACT:
Stability compensation for an amplifier with adjustable gain is provided via adjustable capacitance coupled to an input of a gain element within the amplifier. Gain of the amplifier is adjusted by an adjustable resistance coupled between the input and output of the gain element. The adjustable capacitance and the adjustable resistance determine the frequency of a dominant pole of the amplifier.
