For this purpose a negative resistance structure is used in parallel with output to improve the achievable gain. Because of using self cascode transistors in the output, the proposed structure remains approximately constant in a relatively large output voltage swing causing an invariable gain. To evaluate the proposed method an op amp was designed in 0.18μm CMOS technology. The simulation  results showed a gain of 84dB, unity gain bandwidth of 12.45MHz and phase margin of 81 degree; with 1V power supply and 1pF load capacitor.}, keywords = {Negative Resistance,Op Amp,Self Cascode Transistors}, url = {https://www.ije.ir/article_72098.html}, eprint = {https://www.ije.ir/article_72098_a3fc2754aace3ecbdc4aaeb27d0d3cb9.pdf} }
