Abstract

In various embodiments, a current measurement circuit measures an input current within an integrated circuit. The current measurement circuit includes an integration capacitor, an operational amplifier, a comparison capacitor, an inverter, and multiple switches. The current measurement circuit is coupled to a clocking circuit that, during operation, generates a two-phase clock having a frequency that is proportional to the input current. At least a portion of the switches are turned on during a first phase of the two-phase clock and are turned off during a second phase of the two-phase clock.
