Split-output miller-compensated two-stage amplifiers

In this paper we identify the defining characteristic of a class of split-output miller-compensated (SOM) amplifiers. Existing amplifiers implementing this defining feature are identified, and new two-stage SOM amplifiers are proposed. Various transistor-level implementations of SOM amplifiers are designed in UMC130 CMOS technology and their small-signal circuits are analyzed. Simulation results show that the proposed designs outperform the simple miller-compensated two-stage amplifier in terms of both small-signal performance and large-signal performance.
