Abstract :
We propose a new isolation ring structure for latch-up immunity and power efficiency improvement in smart power IC. The proposed structure improves latch-up rule and power efficiency about 60% and 70% compare to traditional structure. Moreover, it enhances the SOA characteristics and ESD design window as well.
