Abstract

This work presents the design of an energy-efficient 2:1 digital
multiplexer (MUX) utilizing true single-phase clocking (TSPC) logic,
implemented in a 22 nm fully-depleted silicon-on-insulator (FDSOI)
technology. Targeted for high-speed serial link applications, the proposed
MUX achieves a maximum output data rate of 36 Gb/s while consuming only 562
µW of power at peak operation. This corresponds to a figure of merit (FoM)
of 15.6 fJ/bit, demonstrating strong energy efficiency. The design occupies
a compact core area of just 13 µm², making it well-suited for
area-constrained systems. Compared to other recent digital MUX designs, the
proposed implementation offers a compelling balance of speed, power, and
area efficiency for modern high-performance interfaces.
