A Slew-Rate Controlled Transmitter to Compensate for the Crosstalk-Induced Jitter of Coupled Microstrip Lines

Abstract

A single-ended transmitter eliminates the crosstalk-induced jitter at receiver by controlling the slew rates of the signal at transmitter for the even and odd modes of two parallel coupled microstrip lines. The transmitter chip in a 0.18 mu m CMOS process reduces the total RX jitter by about 38 ps (53%) for the data rates from 2.6 to 5 Gbps, and increases the horizontal eye-opening (BER < 1E-12) by about 21% at 5 Gbps.
