A means of high speed switching of a current source is accomplished by switching the source of the output current source transistor while employing circuitry to limit the movement of the source. The primary capacitance is the source diode, and the charge for this comes from a power rail. This results in both a reduction of and a good match of transients coupling to the output. Circuitry is also added to compensate for any current remaining when the current source is switched off.
