Overview on Latch-Up Prevention in CMOS Integrated Circuits by Circuit Solutions

Latch-up is a persistent and detrimental phenomenon in CMOS integrated circuits that can lead to device malfunction, performance degradation, and even permanent damage. This paper provides a comprehensive overview of the various circuit-level solutions employed to prevent latch-up in CMOS technology. To provide practical insights, the paper also discusses the trade-offs inherent in latch-up prevention strategies, considering factors such as area overhead, power consumption, and performance impact. Additionally, it highlights the importance of simulation and testing methodologies for assessing the effectiveness of latch-up prevention measures in CMOS ICs.
