摘要： Some embodiments relate to an electrostatic discharge (ESD) protection device to protect a circuit that is electrically connected to first and second circuit nodes from an ESD event. The ESD protection device includes a first electrical path extending between the first and second circuit nodes and including first and second ESD detection elements arranged thereon. The ESD protection device also includes first and second voltage bias elements having respective inputs electrically connected to respective outputs of the first and second ESD detection elements. A second electrical path extends between the first and second circuit nodes and is in parallel with the first electrical path. The second electrical path includes a voltage controlled shunt network having at least two control terminals electrically connected to respective outputs of the first and second voltage bias elements. Other embodiments are also disclosed.

摘要： An analog output buffer circuit for a flat panel display is provided for improving an output signal distortion. The circuit includes a transistor, a current source, an input capacitor, an upper switch, a lower switch, a first switch, a second switch and a third switch. In which, the transistor and the current source are electrically connected in series between a first power supply and a second power supply. The current source provides a compensatory current for the transistor when a leakage current occurs. The upper switch and the first switch are turned on during the first period, and the lower switch and the second switch are turn on during the second period, in which the second period is after the first period. Those switches eliminate the drawback of different voltage levels between the input signal and the output signal obtained from the output buffer circuit inputted by the input signal.
