Abstract

A current measurement circuit for measuring a current consumption of a circuit system includes a plurality of current measurement units and a current-to-voltage (I-V) converter. Each of the current measurement units includes an impedance unit and a voltage-to-current (V-I) converter. The impedance unit includes a first terminal and a second terminal. The V-I converter, coupled to the first terminal and the second terminal of the impedance unit, includes an output terminal and an operational transconductance amplifier (OTA). The plurality of output terminals of the plurality of V-I converters of the plurality of current measurement units are coupled to a first node. The I-V converter is coupled to the first node.
