Abstract :
The design of a common mode feedback for multistage amplifiers is a difficult process. Based on constructing the common mode feedback path to be topologically similar to the differential mode path, a systematic mapping approach for deriving a fully differential amplifier, from its single-ended counterpart, is presented. The motivation, usage, and efficiency of the proposed approach is demonstrated by two examples.
