A voltage regulator has a switch configured to alternately couple and decouple a voltage source through an inductor to a load, feedback circuitry to generate a feedback current, a current sensor configured to measure the feedback current, and a controller configured to receive the feedback current measurement from the current sensor and, in response thereto, to control a duty cycle of the switch. The feedback circuitry includes an amplifier having a first input configured to receive a desired voltage, a second input, and an output, a capacitor connecting the second input to the output of the amplifier, and a resistor connecting the output of the amplifier and the output terminal such that a feedback current proportional to a difference between the desired voltage and an output voltage at an output terminal flows through the resistor.
