Rh. Derksen, NOVEL SWITCHED-CURRENT SOURCE FOR INCREASING OUTPUT SIGNAL EDGE STEEPNESS OF CURRENT SWITCHES WITHOUT GENERATING LARGE OVERSHOOT, IEEE journal of solid-state circuits, 30(5), 1995, pp. 612-615
Shortly switching off the current supplied to a current switch improve
s edge steepness and reduces overshoot of the output current. This all
ows higher input voltage swing to achieve yet steeper edges while keep
ing overshoot reasonably small. An example shows reduction of rise tim
e and fall time to 50% and 70%, respectively.
