Abstract
A current mirror circuit that allows for fast ramp-up of current for an output, thereby enabling a fast-switched current source with limited current during startup. One embodiment includes first and second transistors coupled in a current mirror configuration; a third transistor including a gate configured to be coupled to an input node, and having a conduction channel coupled between a first voltage source and the gates of the first and second transistors; a fourth transistor coupled to a second voltage source and a gate configured to be coupled to the input node; a fifth transistor including a conduction channel coupled between the conduction channels of the second and fourth transistors, and a gate coupled to a bias circuit; and a capacitor coupled between the gate of the fifth transistor and the drains of the fifth and fourth transistors.
