Abstract

An apparatus for reducing power consumption in a device comprising functional circuitry 520 requiring a first current in a first mode of operation and a second current in a second mode of operation, a capacitor 530 connected in parallel with the functional circuitry thereby defining a parallel circuit; a power supply 500 connected in series with the parallel circuit, switching means 550 between the power supply and the parallel circuit and means to control the switch to connect the parallel circuit to the power supply when the functional circuitry is required to be in its first mode of operation and to disconnect the power supply from the parallel circuit when the functional circuit is required to be in its second mode of operation.
