<p>PURPOSE: To provide equal current paths with a compact structure, and exhibit the possibility of switching one or more current paths. CONSTITUTION: A current path of an array branch 21 is constituted of a load transistor 27, and current paths 32a, 33a of a reference branch 22 are constituted of load transistors 32, 33. The load transistor 32 is connected with a diode, and the load transistor 33 is switchable by a switching network (35-50) connected to a gate terminal of the load transistor 33.</p> |
