Novel high voltage electronic amplifiers that are capable of being monolithically integrated using low voltage semiconductor fabrication processes are described and claimed. A cascade of low voltage current mirrors is described that can act as a high voltage amplifier output circuit. A transconductor and level shift circuit is also described that can be employed in the high voltage amplifier output circuit. A high voltage current source is described and is constructed from the series combination of a low voltage transistor and a parasitic field oxide transistor. Additionally, a differential amplifier having bias-current shunting transistors is described that can be used to limit quiescent current from the output power supply of the high voltage amplifiers.
