ABSTRACT:
A method of suppressing noise in a circuit is disclosed. The method comprises providing a supply voltage to a first terminal of the circuit; providing a ground voltage to a second terminal of the circuit; providing a clock signal to the circuit; and actively decoupling noise from at least one of the first terminal and the second terminal of the circuit by actively decoupling noise synchronously with the clock signal. A circuit for suppressing noise in a circuit is also disclosed.
