Abstract :
The principal motivation of using a fully differential configuration is to reduce power supply coupling. For this reason, an analysis of some of the mechanisms associated with this effect and the usefulness of some forms of common mode feedback are discussed. Experimental results obtained from a CMOS integrated circuit realization are also included. The circuit achieves 50 dB of power supply rejection ratio across the passband.
