ABSTRACT:
A buffer circuit for buffering an applied reference voltage at a low output impedance. The buffer circuit includes an input transistor which is coupled to an external reference voltage and to an external reference current, and a voltage-to-current converter for applying less or more current to an output terminal of the buffer circuit. This provides a substantially temperature-independent and stable buffer circuit which consumes very little quiescent current.
