| Abstract: | In our report,based on GSMC 0.13 μm 3.3 V,rail to rail operational amplifier was designed,which achieved the input and output rail to rail swing,and total gain was 85 dB with a 60 degrees phase margin.Because of the use of gm/Id,the design was more intuitive,and closer to the actual situation of the circuit.Simulations results showed that the indicators were achieved. |
