Amplifier circuit with overshoot suppression

Abstract

An amplifier circuit with overshoot suppress scheme including an input amplifier, an output amplifier, and a diode is provided. A first and a second input ends of the output amplifier are coupled to an output of the input amplifier. The diode is coupled between an output end and the first input end of the output amplifier. When the voltage difference between the output and the input ends of the output amplifier is greater then the barrier voltage of the diode, the diode is turned on, so that the output end of the output amplifier is coupled to the input end of the output amplifier. In the transient state, it rapidly smoothes the overshoot signal. In the steady state, the diode is cut off to maintain the normal operation of the operational amplifier.
