For operational amplifiers, it is desirable to have certain properties such as maximal gain, maximal speed, and optimal current efficiency. Current solutions use either complicated common mode (CM) feedback loops - such as the nested miller amplifier - thereby reducing speed and increasing complexity, or do not feature input drives, making them inefficient for high current loads.
