Abstract: A voltage regulator that provides feedforward cancellation of power supply noise is disclosed. The voltage regulator includes a process tracking circuit that receives a supply voltage and generates a proportional voltage. A tracking capacitor is coupled to the process tracking circuit and generates an injection voltage based on the proportional voltage. An Ahuja compensated regulator generates a regulated voltage. The injection voltage is provided on a feedback path of the Ahuja compensated regulator.
