Abstract
A method can include obtaining a voltage across a first transistor as an obtained voltage. The method can also include multiplying the obtained voltage by a predetermined multiple M to yield a multiplied voltage. The method can further include applying the multiplied voltage to a second transistor, wherein the second transistor is N times smaller than the first transistor. The method can additionally include providing an output current of the second transistor as an M/N scaled estimate of an output current of the first transistor.
