ABSTRACT:
A current mirror amplifier is provided wherein the feedback path around a diode-connected device is modified by adding a resistor in series with the input terminal of the diode-connected device in order to cancel a pole which appears at the unity-gain frequency. This will improve the frequency response and provide for increased bandwidth. The added resistor may be realized in MOS technology by employing a tracking MOS device.
