ABSTRACT:
A reference voltage generator circuit is provided for use with an extremely low power supply voltage. The reference voltage generator circuit produces a lower reference output voltage which is compensated for temperature variations and is independent of changes in the supply voltage. The reference output voltage relies upon the threshold voltage V.sub.T of a MOSFET transistor as a reference source.
