Title: СМОS Operational Amplifier with two types of Miller's compensation Keywords: CMOS, opamp, Miller's compensation Abstract: A two-stage structure of an operational amplifier used for creation of two similar amplifiers is described. The first one has frequency compensation applied on the output stage and the other - between the input and output stages (Nested Miller Compensation). The result is an increasing of the gain bandwidth of both structures compared to the base configuration. When the compensation is applied on the output stage the unity gain frequency is 25 MHz and when it is between the input and output stages the unity gain frequency is over 40MHz. Voltage gain is 87dB. Regardless of the improved transconductance of the Nested Miller Compensation circuite, the classic Miller Compensation is useful when the output must deliver high currents. There are picks in the output characteristics and the full settling time is higher in the Nested Miller Compensation circuite. References
