Abstract
This paper describes a 9.09 Gb/s CMOS demultiplexer using redundant multi-valued logic (RMVL). The proposed circuit receives serial binary data and is converted to parallel redundant multi-valued data using RMVL. The converted data are reconverted to parallel binary data. By the redundant multi-valued data conversion, the RMVL makes it possible to achieve higher operating speeds than that of a conventional binary logic. The implemented demultiplexer consists of eight integrators. Each integrator is composed of an accumulator, a window comparator, a decoder and a D flip flop. The demultiplexer is designed with Samsung $0.35{\mu}m$ standard CMOS process. The validity and effectiveness are verified through the post layout simulation. The demultiplexer is achieved the maximum data rate of 9.09 Gb/s and the average power consumption of 69.93 mW. This circuit is expected to operate at higher speed than 9.09 Gb/s in the deep-submicron process of the high operating frequency.
