Title: Power-on reset circuit
Inventor: TANIZAKI TETSUSHI
IPC: H03K17/22
Filed: 1987-09-19
Abstract: PURPOSE:To stably generate a reset signal even when the leading edge of power supply is slow by connecting a capacitor to a power supply via a charging circuit having a threshold voltage higher than that of a reset signal generator. CONSTITUTION:One terminal of a capacitor 1 is connected to a power supply Vcc via a charging circuit 5 and the circuit 5 consists of two N-channel MOS transistors(TRs) 6, 7 having a prescribed threshold voltage. The threshold voltage of the circuit 5 is set to be a higher voltage than the threshold voltage of TRs 3, 4 being components of an inverter being a reset generating circuit. By such a constitution, since the circuit 5 has a comparatively higher threshold voltage, the circuit 5 is not operated till the power supply rises sufficiently and the charging start to the capacitor 1 is inactive till the power supply rises sufficiently and the start of charging to the capacitor 1 slows down till the power supply rises sufficiently. Thus, even when the leading edge of the power supply is slow, the reset signal is generated stably.
