Abstract

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.
