High voltage integrated circuits

Silicon monolithic integrated circuits have been developed with a voltage capability (LVCEO) in excess of 300 volts. Novel process, device and circuit design techniques have been combined to achieve this voltage capability at a high yield. The design approach, integration and performance of three linear integrated circuits will be discussed: a video amplifier for direct connection to a TV picture tube, a gain block designed to extend the output voltage swing of operation amplifiers to ± 100 volts and a voltage regulator operating in the range from 10 to 300 volts.
