Abstract
PURPOSE:To make the size of a power-on reset circuit small by releasing the reset when a potential of a power supply being a minimum potential reaches a specific value in a combination circuit comprising a P-channel MOS transistor(TR) and an N-channel MOS TR. CONSTITUTION:A source of a P-channel MOS TR P1 connects to a highest potential VDD and a drain connects to a gate of an N-channel MOS TR N1 through a connecting point A. A potential VA at a point A is given to a Schmitt trigger circuit 1. Moreover, a back gate of the TR N1 connects to a minimum potential VSS via TRs N2, N3. With the potential VDD and the intermediate ground potential GND given, the potential VSS is energized and raised. Then the threshold voltage of the TR N1 rises and the source and drain of the TR N1 are turned off and the potential VA rises and approaches the potential VDD. The pulse of the output voltage OUT of the circuit 1 rises on the way of the change to release the reset. The circuits are made small in size through the constitution of TRs.
