ABSTRACT:
A power-on reset circuit is provided which holds an integrated circuit device in a reset mode until at least two conditions are satisfied: supply voltage Vcc must be above a specified value and sense amplifiers in the device must be able to operate properly. Delay circuits and Schmitt trigger circuits also improve the stability of the signal which releases the device from its reset mode.
