Learn some techniques for preventing latch-up, a phenomenon that causes a short circuit and damage to your ICs, such as using CMOS, guard rings, and simulation.

To effectively improve latch-up immunity without enlarging the chip area, circuit methods were therefore invented. An overview on circuit methodology used to prevent latch-up issues in CMOS integrated ...

Latch-up occurs when two bipolar transistor structures enter a self-sustained low impedance state between the anode and cathode. This condition is often the result of parasitic PNP and NPN structures ...
