摘要： Oscillators have capacitors, respectively, whose capacitances change according to an external force and generate first oscillating signals according to the capacitances. Each of the capacitors is disposed, for example, between a substrate and a mass body that is movably disposed to face the substrate and oscillates in a direction perpendicular to the substrate. A detecting unit detects a relative difference between the capacitances of the capacitors as a difference between frequencies of the first oscillating signals. An angular speed or acceleration applied in a horizontal direction of the substrate is calculated according to the frequency change detected by the detecting unit. Therefore, a capacitance difference detecting circuit and a MEMS sensor that detect a minute change in the capacitances of the two capacitors caused by the external force are formed.

摘要： An analog filter circuit in which filter characteristic deviation can be adjusted with simple circuitry and its adjustment method can be provided. The analog filter circuit includes a low pass filter and a high pass filter and output signals of both filters are input to a comparison and adjustment section from which an adjustment signal is fed back to the low pass and high pass filters and also input to a predetermined-band pass filter having predetermined correlation to the low pass and high pass filters. The low pass and high pass filters are tuned so that the frequency-gain characteristic line in an attenuation band of the low pass filter linearly falls, while that line of the high pass filter linearly rises, both the lines crossing at a reference frequency. When filter characteristic deviation occurs, it is adjusted to compensate gain difference between the output signals produced by filtering the reference signal with a reference frequency and, accordingly, the predetermined-band pass filter is adjusted to its desired filter characteristic.

摘要： A voltage control oscillation (VCO) circuit and an adjusting method for the same, which enables an adjustment for suppressing the dispersion of the output characteristic in spite of the manufacture-related dispersion of element characteristics, using a simple circuit configuration, are provided. A low-pass filter 15 and a high-pass filter 16 are composed of the elements that have the same structure as elements composing the VCO circuit 11, and a prescribed correlation is established between both elements. A corrective element 14 is connected in parallel to a main element, in which an oscillation frequency control signal VT is input, in the VCO circuit 11. Respective frequency-gain characteristic lines of the low-pass/high-pass filters 15 and 16 have gradients reverse to each other and cross at a target gain TG. When the capacitance value lowers in dispersion, the level of an output signal SL2 becomes higher than that of an output signal SH2 at a reference frequency fREF to form an output level difference LD2. In response, an adjusting signal VCNT2 is output in correspondence to the output level difference LD2 to lower an oscillation frequency fVCO.
