Title: Automatic reset circuit
Inventor: ABE SUKEYUKI
IPC: H03K17/22
Filed: 1998-10-05
Abstract: PROBLEM TO BE SOLVED: To enable an automatic reset circuit to be easily integrated without using an external part (capacitor or the like) on a semiconductor substrate. SOLUTION: This circuit is composed of an MOS transistor, capacitors for charging and a CMOS inverter, first receives an oscillation signal (CL1) to charge the capacitor 3 when power turned is on and next receives an oscillation signal (CL2) to charge the capacitor 4 from the capacitor 3, and these operations are repeated. When the potential of the capacitor 4 exceeds the threshold voltage of the CMOS inverter, the CMOS inverter is inverted, reset is canceled, and the device has a means which turns on a MOS transistor of feedback and holds reset cancellation once the CMOS inverter is inverted. Thus, it is possible to easily construct an auto reset circuit in a single semiconductor substrate without needing an external part because it is composed of the MOS transistor and the CMOS inverter and the capacitors for charging need only small capacity.
