    摘要: An electrostatic discharge protection circuit that includes at least two transistors connected in a stacked configuration, a first diffusion region of a first dopant type shared by two adjacent transistors, and a second diffusion region of a second dopant type formed in the first diffusion region. A substrate-triggered site is induced into the device structure of the stacked transistors to improve ESD robustness and turn-on speed. An area-efficient layout to realize the stacked transistors is proposed. The stacked transistors may be implemented in ESD protection circuits with a mixed-voltage I/O interface, or in integrated circuits with multiple power supplies. The stacked transistors are fabricated without using a thick-gate mask.

    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.

    摘要: An on-chip latch-up protection circuit. The lath-up protection circuit includes a core circuit, a power switch, and a current extractor. The power switch controls major current flowing through the core circuit. The current extractor detects amplitude of the major current. The power switch, the core circuit and the current extractor are coupled in series between a relatively-high power line and a relatively-low power line. When the major current surpasses a predetermined amplitude, the power switch is turned off, causing latch-up stops.
