摘要： There are disposed a sealing member, a pair of electrode pads to electrically couple a piezoelectric resonator, a plurality of connection pads to electrically couple an integrated circuit element and the piezoelectric resonator, and wiring patterns to establish electrical continuity between the pair of electrode pads and the plurality of connection pads, and the piezoelectric resonator and the integrated circuit element are disposed side by side in plan view. An output wiring pattern establishes electrical continuity between one of the connection pads and an alternating current output terminal of an oscillation circuit, and a power source wiring pattern establishs electrical continuity between one of the connection pads and a direct current power source terminal of the oscillation circuit. The electrode pads are disposed closer to the power source wiring pattern than the output wiring pattern.

摘要： The invention relates to a controller, and more particularly, to systems, devices and methods of controlling a sensor having a resonating mass. The controller includes: an analog-to-digital converter (ADC) unit for extracting a digitized sensor signal from the sensor signal; a phase controller for generating, based on the digitized sensor signal, a phase-controlled signal that is locked in phase with the digitized sensor signal; an amplitude controller for applying a gain to the digitized sensor signal to thereby generate an amplitude-adjusted signal; a modulator for modulating the amplitude-adjusted signal to thereby generate a modulated signal; and a phase shifter for shifting the phase of the modulated signal by 90 degrees. The output signal from the phase shifter is amplified and input to the drive for exciting the resonating mass, to thereby form a closed resonance loop for controlling the oscillation amplitude of the resonating mass.

The crystal element is configured to vibrate at a thickness shear vibration. The excitation electrodes are disposed at both surfaces of a first crystal region of the crystal element. The second crystal region is positioned outside with respect to the excitation electrodes. The second crystal region is formed at a peripheral edge portion of the crystal element so as to occupy a region of equal to or more than 75% of a whole circumference of the crystal element. The second crystal region has a positive/negative direction of an X-axis of a crystal different from a positive/negative direction of an X-axis of a crystal of the first crystal region.
