Abstract
A CMOS circuit protected against latch-up. A limiter parallel to the internal circuitry of the CMOS circuit increases the external current for the triggering of the latch-up in the event of overvoltage on the supply. In one embodiment, the parallel limiter is intrinsically protected against electrostatic discharges. In another embodiment, the limiter is protected by a series connected resistor and a separate shunt-connected ESD protection structure.
