Selective amplifier with a small current consumption for SiGe-process technology

摘要

Selective amplifier with low current consumption for SiGe - technical processes comprising a first (1) and second (2) input transistors, the emitters of which through the first (3) tokostabiliziruyuschy bipole connected with the first (4) power supply bus, the input voltage source (5) connected to the base of the second (2) input transistor, the first (6) and second (7) the frequency control resistors, the first (8) a correction capacitor, wherein the collector of the first (1) of the input transistor is connected to the second (9) power supply bus, wherein that the second manifold (2) input transistor connected to the second (9) power supply bus via a first (6) frequency control resistor and is connected on the alternating current from the second (9) power supply bus via a series-connected first (8) and second (10) additional compensation capacitors, a common node which connected to the output device (11) and first base (1) of the input transistor, wherein the first base (1) of the input transistor is connected to the AC power supply common bus (12) through the second (7) The frequency control resistor.
