Multistage Amplifier Using Dual-Miller with Nulling-Resistor and Dual-Feedforward Structure

Abstract:

This paper designs a high-gain wide-bandwidth multistage amplifier by employing the dual-miller compensation with nulling-resistor and dual-feedforward compensation (DMCNR-DFC) in 0.35μm BCD process. The designed DMCNR-DFC multistage amplifier achieves well performance including gain-bandwidth product (GBW) and slew rate (SR). Simulation results show that the DMCNR-DFC multistage amplifier achieves a dc gain of about 121.1dB and GBW of about 6.1MHz with 52^o phase margin.
