Abstract

This proposes the implementation of a Serializer with Low Voltage Differential Signaling (LVDS) based driver design using CMOS technology with 130 nm Technology. Serializer is a mixed block which uses a Multiplexer(MUX 4:1) Digital Block and LVDS Driver as Analog Block. Serializers are basic building blocks of High speed data transfer communication link. It also helps to reduce the no. of ports in multiport operations that can be multiplexed, serialized with the help of a Multiplexer and transmitted over a cable with LVDS Driver. This circuit will be designed with Skywater 130nm pdk and simulated using the eSim EDA tool developed by FOSSEE IIT Bombay.
