Abstract
A circuit that includes an amplifier circuit with an input impedance due to an input resistance and an input capacitance of the amplifier circuit. The input impedance of the amplifier circuit may vary with frequency. The amplifier circuit may include an amplifier and a feedback circuit configured to provide feedback to the amplifier and to maintain the input impedance at a specified value at a selected frequency by increasing the input resistance of the amplifier circuit at the selected frequency.
