摘要： PROBLEM TO BE SOLVED: To provide a sensing apparatus capable of instantaneously detecting, with a high precision, a very small quantity of, for example, environmental pollutants, or the like.
SOLUTION: A frequency signal from a crystal oscillator is sampled by a frequency signal from a reference clock generating section and the sampled value is outputted as a digital signal. A digital signal is used to perform a quadrature detection for a frequency signal corresponding to the output signal, thereby obtaining a rotational vector that rotates at the frequency of a difference between the frequency of the frequency signal and the frequency of a sinusoidal wave used for the quadrature detection. The velocity of the rotational vector is detected based on each sampled value, thereby detecting the frequency variation. Additionally, the rotational vector is multiplied by a reverse rotational vector corresponding to the velocity of the rotational vector, whereby the measuring range of the frequency variations can be widened.

摘要： PROBLEM TO BE SOLVED: To provide a frequency synthesizer capable of finely setting the frequency across a wide band by employing a new principle, moreover, obtaining in frequency signals of low noise. SOLUTION: The sinusoidal signal of output frequency of a voltage control oscillator is quadrature-detected, and a rotational vector is generated that rotates at a frequency (speed) of the difference from the frequency of frequency signal used for detection. The frequency of the rotational vector is calculated, in advance, when the output frequency of the voltage control oscillator comes to be a set value. A PLL is so formed that the difference becomes zero, when the voltage signal is fed back to the voltage-controlled oscillator corresponding to the difference between the frequency of rotational vector; and the frequency that is calculated when the voltage-controlled oscillator is driven. So, when the PLL is locked, the output frequency of the voltage control oscillation part is adjusted to the set frequency. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a frequency synthesizer capable of improving phase noise. SOLUTION: A sinusoidal signal with a frequency set by a frequency setting section is output as a digital signal from a set signal output section, and the digital signal is D/A-converted. A difference between a sinusoidal signal with a frequency corresponding to the output frequency of a voltage controlled oscillating section and a sinusoidal signal output from a D/A converting section is amplified by a differential amplifier, and the amplified signal is input via an A/D converting section to a module for taking out a phase difference between both the sinusoidal signals. A voltage corresponding to a signal which is obtained by integrating the phase difference is input as a control voltage to the voltage controlled oscillator. Then, the gain of the differential amplifier is set larger than the maximum value of phase noise degradation of the A/D converting section, and thus, the phase noise degradation of the A/D converting section is canceled.
