  • Publication number: 20150249334
    Abstract: Techniques for reducing leakage current during normal operation of an electrostatic discharge (ESD) circuit are described herein. In one embodiment, a circuit comprises an internal circuit and an electrostatic discharge (ESD) rail clamp coupled in parallel to the internal circuit and between first and second power supply rails. The ESD rail clamp is operable to shunt ESD current from the first power supply rail to the second power supply rail via a low resistance shunt path. The ESD rail clamp comprises an ESD trigger circuit configured to detect an ESD event and a plurality of discharging transistors coupled in series. The ESD trigger circuit is configured to turn off the discharging transistors during normal operation and to turn on the discharging transistors to form the low resistance shunt path in response to detection of the ESD event.

  • Publication number: 20120188449
    Abstract: Vertical sync signal separation apparatus and method are provided. The vertical sync signal separation apparatus includes a parameter detecting unit, a threshold generating unit and a vertical sync signal generating unit. The parameter detecting unit measures a composite sync signal to obtain a maximum and a second maximum positive pulse width, and a maximum and a second maximum negative pulse width. The threshold generating unit outputs a positive pulse threshold based on the maximum and second maximum positive pulse width, and outputs a negative pulse threshold based on the maximum and second maximum negative pulse width. The vertical sync signal generating unit outputs a vertical sync signal by comparing the composite sync signal against the positive pulse threshold and the negative pulse threshold. As such, this apparatus can correctly separate a vertical sync signal from composite sync signals with different standards, thus increasing its supportability.

  • Publication number: 20120056238
    Abstract: A bidirectional silicon-controlled rectifier, wherein the conventional field oxide layer, which separates an anode structure from a cathode structure, is replaced by a field oxide layer having floating gates, a virtual gate or a virtual active region. Thus, the present invention can reduce or escape from the bird's beak effect of a field oxide layer, which results in crystalline defects, a concentrated current and a higher magnetic field and then causes abnormal operation of a rectifier. Thereby, the present invention can also reduce signal loss.
