Abstract
A high voltage shift register stage which directly accepts low voltage clock signal inputs without using clock buffers. In particular, a shift register stage circuit is adapted to operate with a low voltage swing clock signal, with the stage circuit having a single state node, a, driven directly. This arrangement allows for reduced power consumption and higher operating speeds.
