Abstract
The present invention provides a current balancing circuit and method for balancing the respective currents in a plurality of parallel circuit branches in a target circuit. The current balancing circuit including: a plurality of balancing transistors, each having a collector, an emitter, and a base, the collector and emitter of each balancing transistor connected in series with a respective circuit branch; and a selection circuit for selectively connecting the circuit branch having the smallest current amongst the circuit branches to the bases of each balancing transistor.
