Abstract :
The authors explore in detail the possible approaches to the design of fully differential amplifiers needed to enhance performance in switched-capacitor circuits. This research has been focused on the behavior of the common-mode feedback circuits. Several structures are evaluated and compared. A strategy is presented that allows the design of differential amplifiers from any given set of specifications. As an illustration a 1-MHz differential amplifier has been designed
