Drive circuit and haptic feedback system

Abstract

A drive circuit and a haptic feedback system. The drive circuit includes a voltage amplification circuit and a current amplification circuit. The voltage amplification circuit is electrically connected to a signal input end and a signal output end and configured to amplify a voltage at the signal input end and output an amplified voltage to the signal output end. The current amplification circuit is electrically connected to an intermediate node and the signal output end and configured to input a compensation current to the signal output end, so that a current at the signal output end is a sum of a current at the signal input end and the compensation current. A current at the intermediate node equals the current at the signal input end.
