A low voltage, low power two-stage operational amplifier (op-amp) was proposed in this paper. A folded-cascode structure is used in the input stage of the amplifier to get high gain. Current mirrors are used in the input stage to make the transconduotance constant. A simple push-pull common source amplifier is adopted as the output stage to take the advantages of its high efficiency. The experimental results show that the unity-gain bandwidth is 12.5MHz, the low-frequency open-loop voltage gain is 100dB,the phase margin is 65°, and power dissipation is 98.8μw.
