ABSTRACT:
A solid-state driver circuit having a relatively low output impedance, for supplying proper drive voltage to a liquid crystal display cell and the like, utilizes metal-oxide-semiconductor transistors and avalanche diodes to provide a driver requiring a relatively small area to facilitate integration of a large number of driver circuits upon a single integrated circuit chip.
