Provided is a current mirror circuit (1) for balancing respective currents in a plurality of parallel circuit branches (2) in a target circuit (3), the current mirror circuit (1) including: a plurality of balancing transistors (4), each having a connector (5), an emitter (6), and a base (7), the collector (5) and emitter (6) of each balancing transistor (4) connected in series with a respective circuit branch (2); a selection circuit (8) that connects the circuit branch (2) having the smallest current amongst the circuit branches (2) to the bases (7) of each balancing transistor; and an isolation circuit (9) that isolates circuit branches (2) having an open circuit fault from the rest of the target circuit (3). An associated method of balancing respective currents in a plurality of parallel circuit branches (2) in a target circuit (3) is also provided. |
