ABSTRACT:
A power-on reset circuit for generating a power-on reset signal includes a capacitor which is charged in response to the application of an external power supply potential to an internal circuit. The capacitor is discharged through a diode-connected MOS transistor having its back gate and gate connected together, to prevent malfunction of the POR circuit when the external power supply potential is reapplied.
