ABSTRACT:
Described are power-on reset methods and circuits for resetting and subsequently enabling integrated circuits in response to applied power. A POR circuit in accordance with one embodiment is capable of operating at exceptionally low temperatures and supply voltages, and is relatively tolerant to process variations. The POR circuit compares a band-gap reference signal to a temperature-compensated reference signal that varies in inverse proportion to temperature. The temperature-compensated reference signal extends the useful temperature range of the POR circuit.
