An apparatus in an electronic device such as a buck converter circuit receives as a first input a voltage signal VSNS from the electronic device that represents a current through the electronic device, and receives as a second input a direct current reference voltage signal from a reference voltage source VREF. The apparatus regulates a direct current output IOUT of the electronic device with respect to the reference voltage source VREF by applying a pulse level transformation to the voltage signal VSNS using an operational transconductance amplifier.
