ABSTRACT:
A complementary high voltage switched current source circuit has a complementary current source pair, wherein a first of the current source pair is coupled to a positive voltage rail and a second of the current source pair is coupled to a negative voltage rail. A digital logic-level control interface circuit is coupled to the complementary current source pair and to the positive voltage rail and the negative voltage rail. A pair of high voltage switches is coupled to the complementary current source pair and the digital logic-level control interface circuit and controlled by the digital control interface circuit.
