Design flow of a Multi-path Nested Miller Compensation three-stage amplifier: frequency domain and large input signal response

This paper aims to provide a standardized approach in the design of a Multi-path Nested Miller Compensation Operational Transconductance Amplifier. In the design flow, starting from standard specifications (i.e. bandwidth, noise, etc.), we will then provide some guidelines and equations for the optimization of large input signal parameters. A case study amplifier has been designed to prove the correct functioning of the presented flow.
