FIELD: radio engineering, communication.
SUBSTANCE: frequency grid synthesiser has a pulsed frequency-phase detector, a charge pumping current source, a capacitive element, a switching element, a control loop filter, voltage controlled generator, a fractionally variable ratio divider (FVRD), a division ratio control circuit in the FVRD, a fractionality compensation current source, the output of which is connected to the output of the charge pumping current source.
EFFECT: eliminating residual pulsations of fractionality noise in the control signal of a voltage-controlled generator.
