ABSTRACT:
An incremental output current generation circuit is disclosed wherein a reference current and a reference voltage are established which follow a bias current which is then multiplied. A set of predetermined voltage reference points are established and the multiplied current supplied thereto. A ramping input voltage is compared to the established voltage referencing points by comparitors. The outputs of the comparators flag the highest voltage reference point which the value of the voltage exceeded. These outputs are sensed by a current generator thereby providing predetermined fractions of the reference current to be delivered at the output as the output source current. In such a manner, an incremental output source current is generated which is dependent on an input voltage level and predetermined incrementally by the value of an established reference current.
