Abstract

A voltage amplifying device that is compensated to reduce variations in its output voltage due to changes in temperature or supply voltage by means of two transistors connected together so that changes in the base-emitter voltage of one transistor are counteracted by similar changes in the base-emitter voltage of the other transistor.
