Abstract：
The invention discloses a reconfigurable operational amplifier which comprises a sleeve type cascode operational amplifier structure, and switches are connected between drain electrodes and source electrodes of part of MOS tubes in the sleeve type cascode operational amplifier structure respectively. Two working states of the cascode operational amplifier and the differential single-tube amplifier are switched by controlling on and off of the switch. The reusability of the operational amplifier is greatly improved, extra design overhead is reduced, and due to the fact that the operational amplifier is designed on the basis of a cascode operational amplifier, extra power consumption cannot be increased.
