ABSTRACT:
A temperature stable voltage reference utilizes an enhancement field effect transistor and a depletion field effect transistor each connected in series with a current source. A differential amplifier has its input terminals separately connected between each of the field effect transistors and their respective current supplies. An input terminal of the field effect transistor is utilized as the reference voltage and is also connected to the gate of one of the field effect transistors, the gate of the other field effect transistor being connected to a reference potential.
