摘要：

In this paper, a new CMOS Op-Amp that operates under low voltage supply having a rail to rail operation is presented. The proposed Op-Amp has a constant transconductance at the input stage over the entire common mode input voltage. A cascode stage that achieves a gain greater than 100dB over almost full range of the common mode input voltage. A common source configuration that increases the output swing between the rails. A class AB control circuit is used to provide a stable biasing at the output stage for the common source configuration to avoid distortion. Simulation results are provided using TMSC 0.25 mu m CMOS technology.
