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

FIELD: wireless communications.

SUBSTANCE: invention relates to radio communication. Method of amplifying and demodulating frequency-modulated signals is characterised by that four-terminal element is resistive, external feedback circuit used is an arbitrary complex four-terminal element connected in parallel to three polar nonlinear element, three-polar nonlinear element and a feedback circuit as integral unit cascade include between source of frequency-modulated 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 modulus m_p, and resonant frequency of device is selected to form given quasi-linear slope section of left slope amplitude-frequency characteristics of device in a given frequency band.

EFFECT: technical result consists in provision of amplification and frequency demodulation of high-frequency signal due to selection scheme and values of resistances of resistive elements.
