摘要：A current regulating circuit having a main current path (h) which contains a firstcontrolled system (s1), a reference current path (r) which contains a similar secondcontrolled system (s2), and a control device (st) which is used for controlling the first and

the second controlled system in parallel and the current regulating circuit exhibiting thefollowing further features: the main current path contains between a supply terminal (vd)and a current input (kd) of the first controlled system (s1) a low-resistance load (d), thecurrent of which is to be regulated; the reference current path (r) contains a high-resistance current source (q), the output of which is coupled to the current input (kp) ofthe second controlled system (s2); and the control device (st) contains as controlamplifier a differential amplifier (dv), the inverting and non-inverting input of which iscoupled to the current input (kd, kp) of the first and, respectively, second controlledsystem (s1, s2). ……
