Addressing the common-mode (CM) noise issue in a Serializer/Deserializer (SerDes) raises a variety of challenges. To address those types of challenges, techniques are presented herein that support cascading multiple metal–oxide–semiconductor field-effect transistors (MOSFETs) in a current-mode logic (CML) output buffer to reduce the CM noise in a SerDes with nearly no impact on, among other things, cost, thermal performance, chip real estate, and power consumption.
