FIELD: radio engineering.
SUBSTANCE: invention relates to radio engineering and electronics and can be used in development of active oscillators, frequency-controlled voltage. Voltage-controlled active oscillator with low level of phase noise comprises a transistor, feedback capacitors, a separating capacitor, parallel oscillating circuit, including an inductance coil, anti-parallel series-connected varicaps, on common electrode to which control voltage E is supplied, second varicap control circuit, amplitude detector and noise negative feedback circuit.
EFFECT: technical result is reduction of phase noise of voltage-controlled generator.
