FIELD: industrial electronics and instrumentation engineering. SUBSTANCE: converter designed for shaping arbitrary-resistance current signal in loads and in sawtooth-voltage generator circuits has amplifier whose noninverting input is connected to load-connection lead and two series- connected resistors of which one is connected to amplifier output and other, to control input. Novelty is introduction of third resistor inserted between point of connection of two first resistors and noninverting input of amplifier. EFFECT: enlarged current regulation range extended towards low values. 2 dwg
