INPUT-OUTPUT ESD PROTECTION |
摘要 |
A method and apparatus for protecting an input-out (I/O) circuit against electro-static discharge (ESD) events. An ESD circuit used to protect the I/O circuit against an ESD event is coupled to the I/O circuit. The ESD circuit includes a diode clamp circuit that couples an I/O pad to a power supply and a ground pad. The ESD circuit further includes an active clamp circuit that is configured to clamp the I/O pad without turning on the diode clamp circuit during the ESD event.
