Abstract

A new Differential Circuit is presented. It has the best properties of both conventional diff. pairs and Class AB cross coupled diff. pairs. The proposed circuit has high gm of Diff. pair while High current capacity of class AB cross coupled diff. pairs. The large signal and small signal analysis are done and are compared to other circuits. The circuit is used to design a new OTA for SC. Circuits. The simulation results are also included.
