RC Triggered ESD Protection Device |
摘要 |
An RC triggered ESD protection device comprises a discharge transistor, a driver circuit and a trigger circuit. The trigger circuit comprises a plurality of native NMOS transistors connected in parallel with a plurality of PMOS transistors operating as resistors. The relatively small resistance of the plurality of native NMOS transistors helps to keep a stable RC time constant value so that the ESD protection device can avoid a leakage current during a power up operation.
