<p>Circuits (1) for balancing first and second currents flowing through first and second channels comprise first and second regulators (4, 7) for regulating amplitudes of the currents, and first and second sensors (5, 8) for sensing the amplitudes of the currents. Controllers (9) control the regulators (4, 7) in response to sensing results from the sensors (5, 8). This way, even in case a sum of the currents is supplied by one and the same current source (2), the first and second currents can be balanced. The first and second channels are parallel channels comprising serial connections of the loads (3, 6), the regulators (4, 7) and the sensors (5, 8). The regulators (4, 7) may possibly comprise transistors (41, 71), the sensors (5, 8) may possibly comprise resistors (51, 81), and the controller (9) may possibly comprise a comparator (91) and a transistor (92).</p> |
