Abstract
A method and circuit for providing a switched current source output has a precharge mode, in which a charge storage device is charged to a reference voltage, and the gate of an output transistor is discharged. In a discharge mode, the charge storage device is discharged to the gate of the output transistor to raise the gate voltage by an amount depending on the charge flow.
