    摘要: A Mixed-voltage input and output (I/O) buffer including a pre-driver unit, a bulk-voltage generating unit, a first to a third transistors and an input stage unit is provided. The pre-driver unit outputs a first source/drain and a second signal. The bulk-voltage generating unit determines whether a first voltage or a pad voltage is used as a bulk voltage according to the pad voltage level. A gate of the first transistor receives the first signal, and a bulk, a first source/drain and a second source/drain of the first transistor are respectively coupled to the bulk voltage, the first voltage and the pad. A gate of the third transistor receives the second signal, and a first source/drain and a second source/drain of the third transistor are respectively coupled to the input stage unit for receiving an input signal from the pad and a second voltage.

    摘要: An ESD protection circuit including a clamping module and a detecting module is provided. The clamping module is coupled between a positive power line and a negative power line. The detecting module includes a triggering unit, a resistor, and a MOS capacitor. An output terminal of the triggering unit is used for triggering the clamping module. The resistor is coupled between the positive power line and an input terminal of the triggering unit. The MOS capacitor has a first end and a second end. The first end is coupled to the input terminal of the triggering unit. During a normal power operation, a switching terminal of the triggering unit enables the second end of the MOS capacitor to be coupled with the positive power line. Thereby, the gate tunneling leakage is eliminated and the problem of mistriggering is prevented.
