Abstract

A new technique for reducing noise crosstalk due to inductive effects in high-speed switching environments is presented. A signalling scheme based on raised cosine approximation (RCA) pulses is used to achieve gradual buffer turn on without any speed penalties. A new current-mode RCA line driver is proposed and incorporated in a 16 bit 1 Gbit/s off-chip transmitter. Simulation results based on TSMC 0.25 /spl mu/m show ground bounce noise reduction greater than 40%.
