N2 - This paper presents a dual-active capacitance in reversed nested Miller compensation (DACRNMC) technique for low-voltage and large capacitive load amplifiers. The frequency bandwidth of the DACRNMC amplifier has been improved due to the usage of active compensation capacitors. The amplifier's die area is reduced in compare to the existing techniques in the RNMC scheme. The architecture also generates two left half plane zeros to increase the phase margin. The simulation for the proposed DACRNMC amplifier with a 0.18µm standard CMOS process reveals a unity gain bandwidth of 17.4MHz and phase margin  of 64 degrees , while 500 pF load is driven  from a single 1.5V power supply.
