Abstract :
A novel PMOS-triggered PMLSCR for high voltage applications is proposed. During normal operation, the PMLSCR keeps good noise immunity with an inherently high trigger voltage. The trigger voltage can be effectively reduced during ESD events and better turn-on uniformity can be obtained. Moreover, mistrigger immunity of the proposed scheme is also verified.
