ABSTRACT:
A current divider circuit includes a node (22) which receives a signal current (I) and divides the signal current (I) between one or more first current paths formed by a first type of impedance element (T1' to TN') and one or more second current paths (28) formed by a type or types of impedance element (21, 22) dissimilar to the first type. Each second current path terminates in an output branch of a current mirror circuit (32). The input branch of each such current mirror circuit is connected to the node (22) via a further current path (30) formed by the first type of impedance element (T0'). The provision of the further current path(s) (30) and current mirror circuit(s) (32) ensures that a predetermined proportion of the total signal current can be made to flow into each current path, even though the second current path(s) (28) may contain arbitrary or unknown impedances. The circuit can also be used to control the voltage at the node (22) as well as dividing the received signal current.
