    Abstract: This paper presents a low voltage CMOS fully differential operational amplifier. It comprises three gain stages with two compensation schemes, buffered reverse nested Miller compensation (B-RNMC) and feedforward transconductance compensation (FFTC). In B-RNMC, a transconductance stage is inserted in the feedback path to eliminate the right half plane (RHP) zero which may degrade phase margin. In FFTC, a feedforward transconductance helps to enhance output large signal response. Using standard 0.35-¿m CMOS technology, measurement results demonstrate that DC gain greater than 90dB, gain-bandwidth product of 8.9MHz, and phase margin of 86° is achieved with l00pF output loads. The settling time for a 1.2Vpp step is 2.4¿s. All the circuits dissipate 34¿W under a single 1.2V power supply.
