A method for reducing phase noise in oscillator with variable-capacitance diode
A method for reducing phase noise in voltage-controlled oscillator by introducing negative feedback noise circuit, offsetting the effect of fluctuations in the amplitude on the variable-capacitance diode capacity is proposed. The relationship between the level of the amplitude fluctuations ...
А circuit of negative feedback by noises for the oscillator with varicaps
It is proposed a circuit of negative feedback for the reduction of phase noise. The circuit compensate the influence of amplitude fluctuations on the value of the average for the period of the oscillation capacitance of the varac-tors and thereby reduces phase noise VCO.
