ABSTRACT:
The present invention is a circuit for regulating the current across an impedance load. This current regulating circuit is comprised of a main current path including a first control path, a reference-current path including a similar, second control path, and a control means including a pulse generator, a current source controller and an operational amplifier for controlling the first and second control paths in parallel.
