ABSTRACT:
To provide for feedback between output and input, a high-resistance feedback circuit is formed of two serially connected oppositely poled semiconductor diodes, integrated with the two complementary MOS transistors on a common semiconductor chip. Preferably, the diodes are located within a window formed in the guard bands on the chip, alongside one of the transistors, and connected with conductive strips to the respective input and output terminals of the transistors.
