Low Power Radio

DA Grant (Inventor)

Research output: Patent


The device comprises a signal processing circuit, such as a radio receiver (Rx) and a class D amplifier driving an output element (6). The voltage supplies to the signal processing circuit and the amplifier are set to respective levels. The voltage swings in the signal processing circuit are much smaller than in the amplifier and consequently the voltage supply to the signal processing circuit can be less than that of the amplifier. This gives rise to a reduction in power consumption. The amplifier may be arranged to provide the voltage supply to the signal processing circuit.
