  • Stabilization Of Oscillater, Synchronisation, Frequency Synthesizers (AREA)

Abstract

PURPOSE:To contrive the improvement of the frequency stability of a phase locked loop by providing a control voltage correction circuit to the output side of a D/A converter in a phase locked loop so that the change value of the oscillation frequency of an atomic oscillator is made equal with respect to positive/negative control signal voltage. CONSTITUTION:A control voltage correction circuit 4 composed of a diode circuit 41, a compressor 42 and an adder 43 inputs a bipolar signal voltage A from a D/A converter 20 and outputs an output voltage C so that the ratio of the output voltage C with respect to a positive input A and the ratio of the output voltage C with respect to a negative input A differ from each other. The output voltage V of the adder 2 differs from positive/negative control signal voltage A and the current ic flowing to a C magnetic field coil 3 differs from the polarity of the control signal voltage A by the output voltage V of the adder 2. Thus, the change DELTAf in the oscillated frequency of the atomic oscillator 1 decided by the square of the current ic of the C magnetic coil 3 is made equal by the polarity of the control signal voltage A to make the PLL control stable.
