ABSTRACT:
A reference circuit is provided which generates a reference voltage which is always at least as high as a stable reference value. This is done by generating a lock signal which is maintained at a first logic level during start-up of the reference circuit and then attains a second logic level when the reference value has stabilized. The reference circuit can be a bandgap reference circuit.
