ABSTRACT:
A current modulation filter for mitigating fluctuations in current on a power supply line due to time dependent current demands of a load circuit includes a biasing circuit for providing a source voltage reference and a quiescent current reference and a load voltage sensing circuit for providing a voltage measurement of the operating voltage of the load circuit. A current sensing circuit is electrically interposed between the power source and the load circuit. A voltage drop across the current sensing circuit is transmitted as a voltage difference to a current controller which subsequently supplies or sinks current to the power supply line so as to maintain a constant current level thereon.
