Abstract (en)

[origin: EP0730214A2] The current mirror has a current bank including input and output side widely controllable cascade stages (t2,t4). A regulating circuit (r,p) generates the fixed potential of the cascade stages. A differential current (id) is fed to the control input of the regulating circuit. A first circuit node (k1) lies between a current mirror input and a first cascade stage (t2) coupled to a corresponding output of the current bank (mb). The regulation circuit includes a current controlled current source (q). The control input of the source, at a second circuit node (k2) is connected to the first node (k1). The output of the source, at a third node, is connected to a common control line (c1) for the current bank (mb). A capacitive load (c3), particularly one formed by capacitively charging the control line (c1), is connected to the third node (k3) to adjust a regulation time constant.
