| Abstract: | In this paper, the authors design a low-voltage rail-to-rail operational amplifier with the MXIC 0.5μm DPDM Mixed signal technology and they also use 0.5μm N-well CMOS process manufactured by Macronix International Co., Ltd. to do the layout. The Hspice simulation shows that the operational amplifier can operated with power supply voltages as low as ＋1.5V while providing a full swing output voltage and in- putting off set voltage of 35μV. The result also shows a DC gain is 85dB and the frequency of 82dB is 8K. |
