Abstract
The invention concerns a power diverting circuit for creating a supply voltage for a signal processing circuit from a source of data signals each having a high or a low potential respectively corresponding to a first or a second logic state. The circuit comprises a first terminal for receiving the data signals, a second terminal for providing the supply voltage, a switch coupled between the first terminal and the second terminal for selectively connecting and disconnecting the first terminal and the second terminal, and an inverter for inverting the state of the data signals. The inverter, which has an input terminal connected to the first terminal and an output terminal for providing the inverted data signals to the signal processing circuit, is responsive to the state of the data signals received at the first terminal to control the operation of said switch means.
