Current-source arrangement.

摘要

N configurations of N+1 transistor configurations (2.1 to 2.N+1) comprising control transistors (T1 to T N+1) and control inputs (3.1 to 3.N+1) are connected to N outputs (1, 2, ... N) by means of a switching network (7) in accordance with a cyclic pattern N, the remaining configuration being connected to a correction circuit (5) comprising a reference-current-source (6) for adjusting the control voltage of the control transistor via the control input of the relevant configuration, in such a way that the output current of the relevant configuration becomes equal to that of the reference-current-source (6).
