1	Ring amplification for switched capacitor circuits Hershberg, Benjamin Poris 19 July 2013 (has links) A comprehensive and scalable solution for high-performance switched capacitor amplification is presented. Central to this discussion is the concept of ring amplification. A ring amplifier is a small modular amplifier derived from a ring oscillator that naturally embodies all the essential elements of scalability. It can amplify with accurate rail-to-rail output swing, drive large capacitive loads with extreme efficiency using slew-based charging, naturally scale in performance according to process trends, and is simple enough to be quickly constructed from only a handful of inverters, capacitors, and switches. In addition, the gain-enhancement technique of Split-CLS is introduced, and used to extend the efficacy of ring amplifiers in specific and other amplifiers in general. Four different pipelined ADC designs are presented which explore the practical implementation options and design considerations relevant to ring amplification and Split-CLS, and are used to establish ring amplification as a new paradigm for scalable amplification. / Graduation date: 2012 / Access restricted to the OSU Community, at author's request, from July 19, 2012 - July 19, 2013 ring amplification ring amplifier ring amp ringamp RAMP Split-CLS CLS correlated level shifting switched-capacitor scaled CMOS scaling scalability analog to digital conversion A/D analog to digital converter ADC low power rail-to-rail slew-based stabilized ring oscillator high resolution Switched capacitor circuits
