Abstract:
A voltage regulator is controlled to improve supply voltage rejection by cancelling an alternating component of a supply voltage signal that is capacitively coupled to a high-impedance node within the voltage regulator. This cancellation is done by capacitively coupling an inverted version of the alternating component to the high-impedance node to thereby substantially cancel the alternating component present on the high-impedance node. The high-impedance node may be a high-impedance voltage reference node of the voltage regulator.
