A power-on reset circuit for providing the stable generation of a reset signal without being affected by the rising characteristic of a power-supply voltage. In the novel power-on reset circuit, a flip-flop (13) composed of a pair of cross-connected inverters (11, 12) is used, a common connection point between a diode (Q15) and a capacitor (C11) connected to each other in series is connected to a node (N11), which is one output of the flip-flop, an output signal at a node (N12), which is another output of the flip-flip, is supplied to a reset pulse generator (16) via an inverter (15), a change in the output signal is detected by the reset pulse generator, and a reset pulse is generated based on the detected signal change. <IMAGE> |
