Abstract

This paper presents a new pseudo-NMOS fully differential CMOS current-mode multiplexing transmitter. High multiplexing speed is achieved by multiplexing at a low-impedance node and inductive shunt peaking with active inductors. The differential configuration of the transmitter minimizes the effect of common-mode disturbances and the effect of electromagnetic interference from channels. The transmitter draws a constant current from the supply voltage, thereby minimizing both switching noise and noise injected to the substrate. The transmitter has been implemented in TSMC´s 1.8 V 0.18 μm CMOS technology and analyzed using Spectre from Cadence design systems with BSIM3.3v device models. Simulation results are also presented in the paper.
