Abstract
A comparison among feedforward (CMFF) and the traditional common-mode feedback (CMFB) loops, based on the most frequently used common-mode (CM) signal detectors for CM control in fully-differential (FD) circuits, is carried out. Simulated results confirm that CMFF shows a better performance in terms of induced nonlinear signal distortion, speed, and amplifier output signal swing. It is demonstrated that feedforward approach results very attractive for low-voltage applications
