Abstract
A high voltage CMOS switch circuit having an arrangement of device connections such that the individual transistor devices are substantially the same size, improving performance while reducing size and providing breakdown protection. The circuit switches a high voltage to the output based on a low voltage input. The circuit is ratio-less and self-biased, capable of operating a very low supply voltage compared to the state of the art.
