The initial phase of the operational amplifier is the differential amplifier. It merely amplifies the difference between the two signals and rejects any common signals. As the CMOS technology is extended to the nanoscale range, several important features must not be addressed and overcome if an analogue and physical systems are to be successfully designed. In the nanoscale age of the analogue CMOS concept, it is becoming increasingly vital to understand the physical variables which influence circuit reliability and performance and how they will be mitigated or overcome. The use of the modified MOS structure with pull-up and pull-down stacked transistors, the differences amplifier gain factor is enhanced to 5 dB compared to conventional differential amp circuits. This article discusses MOS differential amplifier structure and analysis and how it may be designed for a specific specification. An illustration of the design process and simulation with the NG Spice Tool is taken for an example. Design with the MAGIC VLSI tool is finally developed.
