ABSTRACT:
The start-up aid circuit is connected to a plurality of current sources. The start-up aid circuit is common to all the current sources and supplies a start-up current to each current sources when the current sources are operating in a transient operating state following power-up of the apparatus. The circuit also inhibits the start-up aid circuit when all the current sources have reached an operating state described as stationary. The circuit may be applied to the power supply of microprocessors and electronic equipment.
