BIPOLAR CURRENT MIRROR WITH CONTROLLED TRANSFER RATIO Russian patent published in 2011 - IPC H03F3/343 G05F3/26 H03G3/30 

FIELD: electricity.

SUBSTANCE: electronic adjustment of transfer ratios in current sources controlled by current on the basis of a current mirror is carried out through usage of control transistors in basis circuits of the current mirror transistors, and control transistors have a structure opposite to a structure of the current mirror transistors (2) and perform function of controlled voltage sources. The transfer ratio is controlled by a differential voltage supplied to bases of control transistors (5). Connection of transistors that form current current mirrors with input and output transistors, makes it possible to expand a dynamic range of a control signal.

EFFECT: expansion of frequency band.
