High performance 4:1 multiplexer with ambipolar double-gate FETs

Abstract

In this paper, we exploit the ambipolarity property of double gate devices such as DG-CNTFETs to design a new 4:1 multiplexer, with a significant reduction in circuit complexity with respect to conventional CMOS-based multiplexers for equivalent functionality. Based on Pass-Transistor Logic, it demonstrates performance improvement of up to 3× concerning Power-Delay-Product reduction, as compared to conventional multiplexers, and an area reduction of at least 2× compared to any 4:1 multiplexer, and up to 3× when compared to a static-logic design.
