Abstract
This study describes a new and simple frequency compensation for three stages amplifiers based on revered nested Miller compensation (RNMC) structure. Using only one and small compensation capacitor reduced circuit complexity and die area while shows better performance compared to RNMC. Also the proposed method is unconditional stable due to cancellation of second dominant pole by a zero. Ample simulations are performed using HSPICE and TSMC 0.18 µm CMOS technology to verify robustness of presented circuit. Simulation results show 114 dB, 6.66 MHz and 360 µW as DC gain, GBW and power consumption respectively.
