A common-mode feedback circuit suitable for fully balanced analog MOS structure realization is discussed. A novel scheme of differential-difference amplifier, the concept of which can be employed in CMFB system, is proposed. A transconductance amplifier is shown as an application example. SPICE simulation is used to verify the theory
