摘要
In this paper, improved CMRR, high gain CMOS current-mode operational amplifier (COA) is presented. A new class AB input stage is used in order to obtain very low input resistance. The proposed COA is operated under +/- 1.5 V voltage supplies and designed with 0.35-mu m CMOS process. Results of simulation indicate a 107 dB DC gain, 123 Omega input resistance, common mode rejection ratio exceeding 110dB and a gain-bandwidth product at about 100 MHz.
