摘要：
A high voltage differential pair and op amp implemented in a low voltage semiconductor process. The high voltage differential pair expands the incoming common mode voltage of a differential pair to multiple times the normal operating voltage of the differential pair through the use of high voltage current sources, current sinks and stacks of transistors. The high voltage op amp includes a high voltage input stage and a high voltage common source amplifier to expand the output voltage range to multiple times the normal operating voltage of the op amp.
