    摘要: An active device array substrate includes pixel units, scan lines, data lines, electrostatic discharge (ESD) protection elements, a short ring and an ESD biased generator. Each pixel unit is electrically connected to the corresponding scan line and data line. Each ESD protection element has a first connection terminal, a second connection terminal and a third connection terminal, wherein the first connection terminal is electrically connected to one of the corresponding scan line and data line, the second connection terminal is electrically connected to the short ring, and the third connection terminal is electrically connected to the ESD biased generator. As an ESD stress occurs, the ESD biased generator provides a voltage to the ESD protection elements to turn on them. It causes that the accumulated electrostatic charges are conducted into the lowest potential of the substrate through the short rings, so as to prevent the pixel units from ESD damaging.

    摘要: An output buffer circuit with low-voltage devices to driver high-voltage signals for PCI-X applications is proposed. Because power supply voltage of PCI-X is at 3.3V, the high-voltage gate-oxide stress is a serious problem to design PCI-X I/O circuit in a 0.13 μm 1V/2.5V CMOS process with only low-voltage gate oxide. This proposed output buffer circuit can be operated at 133 MHz in 3.3V PCI-X environment without causing high-voltage gate-oxide reliability problem. In this design, the circuit is implemented in a 0.13 μm 1V/2.5V CMOS process and the output signal swing can be 3.3V. Besides, a level converter that converts 0V˜1V voltage swing to 1V˜3.3V voltage swing is also presented.

    摘要: A thin-film transistor (TFT) with body contacts is disclosed. It is used in polysilicon TFT LCD's. A body contact region for separating the gate electrode, a source region, and a drain region is made in the TFT. Through the dopants in the body contact region and different impurities in the source region and the drain region, a body-trigger bias is imposed on the body of the TFT. This method reduces the threshold voltage of the TFT driving circuit, thereby increasing the driving current.

    摘要: An ESD protection circuit design incorporating a single, or a plurality of, parallel inductor and capacitor, also known as LC tank(s), to avoid power loss by parasitic capacitance in ESD circuits. The first design described incorporates a LC tank structure. The second includes two LC tank structures. These structures can be expanded to form ESD protection circuit structures stacked with n-stages LC tanks. The last design described is ESD protection circuits formed by stacking the first design. These designs can avoid power gain loss from parasitic capacitance of ESD, because the parameters of LC tank can be designed to resonant at a desired operating frequency. Each of these designs can be altered slightly to create variant designs with equal identical ESD protection capabilities.
