Abstract

With the aim of creating a high-quality display system with value-added functions, we designed a current mode multiplexer for LTPS TFT devices. The multiplexers had less than 1 volt logic swing, and speed improvement was evident compared with that of conventional CMOS architecture. We refined the multiplexer to achieve a more stable current steering operation. By using the versatility of the multiplexer, a new NAND/AND and NOR/OR logic gates were designed through the simple modification of signal connections. Two micron LTPS TFT parameters were used during the HSPICE simulation of the circuits.
