ABSTRACT:
A CMOS power-on detection circuit is described in which a rising supply potential is utilized to charge a capacitor and the voltage on the capacitor is coupled by one or more current mirrors to drive one of a pair of series connected complementary MOS transistors, a change in potential at a node between the transistors providing the power-on indication.
