HIGH FREQUENCY MULTIDIFFERENTIAL AMPLIFIER Russian patent published in 2009 - IPC H03F3/45 

FIELD: radio engineering.

SUBSTANCE: high frequency multidifferential amplifier contains first current mirror (1), current output (2) of which is connected to first load circuit (3), current input (4) is connected to two-terminal circuit of pedestal current (5), and common emitter input (6) is connected to first source of input signal (7). In the scheme there introduced is N≥1 of additional current mirrors (8.1, 8.2, …, 8.N) current inputs of which (9.1, 9.2, …, 9.N) are connected to current input (4) of first current mirror (1), and common emitter inputs (10.1, 10.2, …, 10.N) are connected to additional sources of input signals (11.1, 11.2, …, 11.N).

EFFECT: enlarging frequency range.
