Aksin, D: Adc For Power Management Ics and Symbolic Small Si

This work is organized in two sections: The first section deals with the 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 procedures of a high input signal range PMIC ADC together with its measurement results are provided. The manuscript contains the details of the related to high voltage signal processing as well as associated device reliability issues. The ed ADC achieves an input signal range that is twice its supply voltage and its architecture is unique in terms of allowing the ers to increase the converter resolution by increasing the most significant bit. The second section reviews the state of the art in symbolic circuit analyzer software and introduces a new tool that is capable of extracting linear as well as nonlinear transfer functions of the circuit/system analyzed. The Matlab Simulink and Cadence Virtuoso interfaces make it really useful to the analog circuit er as well as to system ers.
