Abstract
A shift register circuit has a plurality of shift registers connected in series, each shift register having a phase-shifting element and a pull-high element, wherein the phase-shifting element receives a first input signal, a first clock signal and a second clock signal, and the first clock signal and the second clock signal are complementary in phase. The pull-high element is used for pulling up an output signal to a high logic level, and includes a logic unit, wherein no current path is established in the pull-high element when the shift register is operated in any type of periods.
