This work is organized in two sections: The first section deals with the design of an ADC for PMIC applications, and the second section introduces a symbolic small signal analysis tool developed using Matlab. The state of the art and unique problems related to the PMIC ADC are reviewed in the first section. The design procedures of a high input signal range PMIC ADC together with its measurement results are provided. The manuscript contains the details of the design related to high voltage signal processing as well as associated device reliability issues. The designed ADC achieves ...
