FIELD: electricity.SUBSTANCE: current mirror comprises the first (1) input transistor, a collector of which is connected to the input (2) of the device, the base of the first (3) output transistor and closed p-n transition to a substrate (4) of the first (1) input transistor, the second (5) output transistor, the collector of which is connected with the combined bases of the first (1) input and second (5) output transistors, and also the closed p-n transition to the substrate (6) of the second (5) output transistor, the bus of the source of supply (7), connected to the emitter of the first (1) input and second (5) output transistors, the closed p-n transition to the substrate (8) of the first (3) output transistor, the first output of which is connected with the collector of the first (3) output transistor and the current output (9) of the device. The second output of the closed p-n transition to the substrate (8) of the first (3) output transistor is connected to the collector of the second (5) output transistor.EFFECT: higher accuracy of transfer at flow input currents of a Wilson current mirror when implemented on p-n-p transistors with isolation by p-n transitions onto a substrate.10 dwg |
