Abstract
Driver circuits for small LCD (Liquid Crystal Display) are formed on the same glass substrate as LCD by means of TFTs (Thin Film Transistors), which is called SoG (System on Glass) technology. If the driver circuit is designed by nMOS transistor only, then production cost is reduced, because the pMOS process can be eliminated. In this paper, we propose a new nMOS 2-phase clock dynamic logic shift register, which is indispensable in active-matrix LCD driver circuits. Moreover, we propose a design method determining gate widths of nMOS transistors in 2-phase clock dynamic logic shift registers, and show performance evaluation results.
