FIELD: electricity.
SUBSTANCE: generator contains an automatic gain control unit which first input is connected to the first output of crystal resonator and input of a unit for compensation of crystal resonator static capacity which output is connected to the second output of crystal resonator and input of the amplifier; the amplifier is made as cascades connected in-series, at that at least one or several last cascades are made with regulated transmission coefficient and each of them contain the first, second and third resistors, a switching element and an amplifier inverter which input is connected through the first resistor to output of the previous cascade or to output of the previous cascade with regulated transmission coefficient; output of the amplifier inverter in each cascade with regulated transmission coefficient is connected to its input through the second resistor and the switching element and third resistor connected in-series; control input of the switching element is connected to the second output of the automatic gain control unit.
EFFECT: stabilising amplitude and shape of output signals in varying operating conditions and increasing stability of generation frequency.
