NON-INVERTING CURRENT AMPLIFIER-BASED SELECTIVE AMPLIFIER Russian patent published in 2013 - IPC H03F3/45 H03G3/14

Abstract RU 2488955 C1

FIELD: radio engineering, communication.

SUBSTANCE: non-inverting current amplifier-based selective amplifier has an input voltage source (1), a voltage-to-current converter (2), an output transistor (3), an auxiliary voltage source (4), a first (7) and second (8) balancing capacitor, a second (9) frequency-setting resistor.

EFFECT: high Q-factor of the amplitude-frequency curve of the selective amplifier and its voltage gain at quasi-resonance frequency f₀.
