Abstract

Latch-up effect is a kind of parasitic effect in CMOS integrated circuits. Taking CMOS inverter as an example, this paper analyzes the formation mechanism of latch-up effect in CMOS integrated circuits, deduces the trigger conditions of latch-up effect by establishing equivalent circuit models, introduces the methods of suppressing latch-up effect from layout design and process optimization, and finally conducts simulation test to verify the effect of suppression methods.
