Abstract: A power amplifier circuit comprising first and second modules, a current source and a push-pull module. The push-pull module comprises two intermediate transistors and two output transistors. The circuit also comprises third and fourth modules, operating in current mirror mode. Inputs of the third module are respectively connected to one main electrode of one of the intermediate transistors and to a node internal to the first module. Outputs of the fourth module are respectively connected to a main electrode of the other intermediate transistor and to a node internal to the second module. The circuit is designed to form a power output stage of an operational amplifier.

Abstract: The invention relates to a control circuit for a bias source including a stand-by device and a starting-aid device, with their respective outputs connected to a control input of the bias source, the starting-aid device including a switch to inhibit its operation, controlled by the bias source, said circuit including capacitive means for reactivating the starting-aid device when the “Stand-by” control signal changes state, indicating that the bias source should be reactivated.

Abstract: The invention relates to a device for setting at stand-by a bias source through a stand-by control signal, including an inverter with an active load controlled by the bias source. The inverter includes a first p-channel MOS transistor, whose source is connected to a positive terminal of the supply voltage of the bias source, whose drain constitutes the inverter output connected to a control input of the bias source, and whose gate constitutes the input of the inverter receiving the stand-by inducing control signal.
