Abstract
A method for fast-enabling a current source includes conducting a first current through a first branch including a first transistor connected in series with a first switch, in response to enabling the first switch with an enable signal. A first charge is removed from a bias rail with a first capacitance between a first gate and a first source of the first transistor. A second current is conducted through a second branch including a second switch connected in series with a second transistor, in response to enabling the second switch with the enable signal. A second charge is added to the bias rail with a second capacitance between a second drain and a second gate of the second transistor, wherein the first gate and the second gate are connected to the bias rail and biased by the mirror reference voltage.
