Abstract
An integrated circuit comprises a logic circuit connectable to a battery power supply to energize the logic circuit. A converter generates a stepped up voltage supply from the battery power supply and an analog circuit is receptive of the stepped up voltage supply for controlling the operation of other circuitry. The analog circuit and the logic circuit comprise CMOS transistors integrated on the same chip.
