Abstract

A current reflector comprises a zero bus, input and output buses and four transistors, with an input bus being connected to a collector and a base of first transistor, and a base of second transistor; the emitter of first transistor is connected to the collector and base of third transistor, as well as to the base of fourth transistor, the emitter of second transistor is connected to the collector of fourth transistor, the emitters of third and fourth transistors and connected to the zero bus, the collector of second transistor is connected to an output bus. Moreover, four transistors, three current sources are introduced. The emitter of fifth transistor is connected to the collector of second and sixth transistors, as well as to the first terminal of second current source. The base of fifth transistor and emitter of sixth transistor are connected to the second terminal of first current source; the bases of sixth and seventh transistor are connected to the collector of seventh transistor and second terminal of third current source. The emitter of seventh transistor is connected to the collector and base of eighth transistor, the collector of fifth transistor is connected to the output bus; the first terminal of first current source, first terminal of third current source, second terminal of second current source and emitter of eighth transistor are connected to the zero bus.
