Abstract
A current regulator (60, 90, and 100) provides current regulation. The current regulator (60, 90, and 100) has a bias generator (14) which compares a generated voltage, V.sub.ref, with a feedback voltage generated in accordance with an output current provided in a reference circuit (57, 58, and 59). The current regulator (60, 90, and 100) operates as a bias circuit to minimize the quiescent currents for efficiently providing regulated output currents in current sink circuit (26). The current in the bias generator (14) and the current in the reference circuit (57, 58, and 59) that regulate the output current in current sink circuit (26) are a small percentage of the overall current.
