Abstract

It is not unusual to find applications where of inactivity, but will then latch this POR and use it while it is desirable to have an initial Power-ON to disable the power supply to the POR detector cir- Reset there is a strong desire to avoid them being cuit so that it cannot create more resets until the created every time there is a disturbance on the POR latched signal has decayed. With modem CMOS cir- generator's power supply! The idea of this circuit is cuitry this makes it possible to ignore spurious POR that it will detect an initial POR after a long period events for many 10's of microseconds.
