Design and Physical Implementation of an Analog Receiver for a SerDes System on Chip in 130nm CMOS Technology

摘要

An analog receiver module for a SerDes with a data rate of 2.5 Gbps for PCI Express Gen 1, is presented. The module is composed by a high-speed differential amplifier, a replica bias circuit and a CML to CMOS converter with duty-cycle correction. The circuit was designed in CMOS 130nm process technology with a supply voltage of 1.2V. A high gain amplifier using the selfcascode technique allows to overcome the low output impedance limitation set by the 130nm technology. Simulation results show no functional issues under PVT corners and mismatch conditions, accomplishing PCI Express Gen 1 specifications.
