Abstract
A self-tracking high voltage breakdown protection circuit is provided. A non-destructive reference voltage is established by a gated diode having the same breakdown and walkout characteristics as the integrated circuit devices to be protected. A source-follower configuration couples the reference voltage to the integrated circuit. Devices of the protection circuit are internally connected to make each self-protected.
