METHOD OF AMPLIFYING AND DEMODULATING FREQUENCY-MODULATED SIGNALS AND DEVICE THEREFOR Russian patent published in 2016 - IPC H03J3/00 H03D3/00 H03F3/38 

Abstract RU 2605675 C2

FIELD: radio engineering and communications.

SUBSTANCE: method of frequency-modulated signals amplifying and demodulating is characterised by that as external feedback circuit used is arbitrary complex four-terminal element connected in parallel to three polar nonlinear element, which with feedback circuit include as integral unit a cascade between source of signal with complex resistance and input of resistive four-terminal element, between output of resistive four-terminal element and low-pass filter includes high-frequency load in form of a bi-pole with complex resistance, in series to resistance of source of frequency-modulated signal first reactive matching two-terminal element is included, in series to resistance of high-frequency load second reactive matching two-terminal element is included.

EFFECT: possibility of amplification and frequency demodulation with increased linear section of the frequency demodulation characteristics and increased dynamic range at arbitrary characteristics of the nonlinear element, external feedback circuit, load and parameters of resistive four-terminal element.
