A low power 13-Gb/s 2/sup 7/-1 pseudo random bit sequence generator IC in 120 nm bulk CMOS

Abstract

We present a pseudo random bit sequence (PRBS) generator with a sequence length of 2/sup 7/-1. The circuit uses a 7 bit full rate shift register with a linear XOR feedback and works up to data rates of 13 Gb/s. The PRBS generator features a divide by 2 trigger divider, two 3 bit shifted outputs and an autostart logic. The circuit draws 137 mA from a single 1.5 V supply. The circuit is manufactured in 120 nm bulk CMOS technology.
