摘要:
A current mirror circuit wherein an I.sup.2 L circuit is employed as the load of a current mirror circuit formed of a PNP (NPN) transistor, the injector of the I.sup.2 L circuit is common with those of another group of I.sup.2 L circuits, and a predetermined current is derived from the PNP (NPN) transistor of the current mirror circuit.
