Abstract
A power-on reset circuit provides the stable generation of a reset signal without being affected by the rising characteristic of a power-supply voltage. A flip-flop having a pair of cross-connected inverters is used, a common connection point between a diode and a capacitor connected to each other in series is connected to a node, which is one output of the flip-flop, an output signal at a node, which is another output of the flip-flip, is supplied to a reset pulse generator via an inverter, so that a reset pulse is generated based on a detected output signal change.
