Based on the CMOS SMIC 0.18um technique, this paper presents a high-performance folded cascode amplifier, which replaces the traditional telescopic structure with the classic cascode structure. Through the spectre simulation of Cadence, under 3.3V, the circuit’s DC gain is as high as 96.29dB, and the phase margin is 83.5 degree with a high stability; the bandwidth gain is larger than 5MHz, the power consumption is smaller than 0.1mW.
