A new CMFB circuit is used to stabilize the common mode level of the output; Effected measures are used to constrain the wing of the output of the pre.
Used the switched capacitor Common Mode Feedback circuit(CMFB) in main amplifier to achieve a large output voltage swing and decrease the static power consumption at the same time.
