The differential amplifier circuit characterized in terms of self-bias capability, common-mode rejection, voltage gain, and the gain-bandwidth product. In this paper a new model for high performance low voltage CMOS differential amplifier has been proposed. This model is simulated using SPICE simulator and optimized device parameter with .25 micron CMOS technology.</p> <p>&nbsp;</p> https://ultraphysicalsciences.org/paper/1160/ Differential pair CMRR Transconductance Slew Rate
