Abstract: An optical rotation angle of linearly polarized light is modulated to obtain modulated light. The modulated light is passed through an inspection object containing an optically active substance. The optically active substance rotates an optical rotation angle of the modulated light. An intensity of light coming out of the inspection object is measured. Variation in the optical rotation angle of the modulated light is calculated based on the measured intensity and the angle to which the linearly polarized light is modulated. A concentration of the optically active substance in the pulsing component of the inspection object is calculated based on the variation in the optical rotation angle. Thus, concentration of glucose in the blood can be calculated without harming the patient.

Abstract: A crystal oscillator circuit using CMOSFETs including an oscillator circuit that is constructed of a resonating section and an amplifying section having a CMOSFET, a reference current source circuit for generating a reference current which determines a bias current of the amplifying section, and a control signal generator circuit for controlling the reference current source circuit to make a bias current larger than that in the oscillation status when the oscillator circuit is in the non-oscillation status.

Therefore, it can lower the driving source voltage of the oscillator circuit. Further, only the bias current of the amplifying section is increased during the oscillation starting period of the oscillator circuit, so that the oscillator circuit can provide a stable oscillation with low power, without variations in the source voltage.
