Abstract

See full text

This application provides a current measurement circuit including: an amplification unit, configured to amplify an electrical signal from the sensor unit; a comparison unit, configured to obtain an initial pulse signal based on a voltage signal output by the amplification unit and a preset voltage; a delay unit, electrically connected to the comparison unit and configured to delay an output of the initial pulse signal to obtain a target pulse signal; a resistance unit, wherein two terminals of the resistance unit are electrically connected to an input terminal of the amplification unit and an output terminal of the delay unit respectively, and the resistance unit is configured to charge and discharge the amplification unit based on the target pulse signal; and a calculation unit, electrically connected to the delay unit and configured to calculate a target current based on the target pulse signal output by the delay unit.
