ABSTRACT:
A method and circuits for generating a start-up signal to force a bistable reference circuit into a conducting state. The start-up signal ensures that the reference circuit operates to provide a desired output signal when power is applied. The start-up signal is self-generated and self-canceled, rather than relying on an externally supplied pulse, and is input to the reference circuit via a hysteresis circuit (e.g., Schmitt inverter).
