    摘要： Disclosed herein is a method of manufacturing an inertial sensor. The method includes: (A) preparing a base substrate; (B) forming a depressed first concave part in one surface of the base substrate; (C) forming a mass body in the first concave part by filling a metal or a combination of a metal and a polymer (or a polymer matrix composite) therein; and (D) forming a depressed second concave part in one surface of the base substrate at an outer side of the mass body and forming a flexible part on an upper portion of the second concave part in the base substrate. The mass body formed of the metal or the combination of the metal and the polymer (or the polymer matrix composite) has high density, thereby making it possible to improve sensitivity of the inertial sensor.

    摘要： Disclosed herein is an inertial sensor, which includes a diaphragm having a piezoelectric element or a piezoresistive element formed on one surface thereof, a mass element integrated with the center of the other surface of the diaphragm in which the distal end of the mass element has a larger width than the width of the proximal end in contact with the diaphragm, and a supporter formed along the edge of the other surface of the diaphragm, so that the use of the mass element having the above shape results in decreased spring constant and increased distance from the center of the diaphragm to the center of the mass element, thereby simultaneously realizing a reduction in the size of the inertial sensor and an increase in performance thereof. A method of manufacturing the inertial sensor is also provided.

    摘要： A PLL circuit includes a phase detector that compares the phase of an input clock and the phase of a feedback clock and generates a pull-up control signal and a pull-down control signal. A loop filter pumps a voltage in response to the pull-up and pull-down control signals, filters the pumped voltage, and outputs a control voltage. A voltage controlled oscillator receives the control signal and oscillates an output clock. A clock divider divides the frequency of the output clock at a predetermined rate to generate the feedback clock. In the PLL circuit, the loop filter includes a compensator that compensates for a variation.
