Abstract :
Presents a summary of over twenty patents and includes abstracts as well as diagrams, where applicable. Covers such technologies, techniques, and/or methodologies as: differential amplifiers with enhanced gain and controlled common-mode output level; a switched capacitor mutual charging system and method; a method and apparatus for a gain controlled mixer; calibration of a phase locked loop; a multi-path digital power supply controller; a Class D amplifier; a voltage regulator for high performance RF systems; a method and a circuit for producing a PTAT voltage, and a method and a circuit for producing a bandgap voltage reference; and differential front-end continuous-time sigma-delta ADC using chopper stabilization.
