GYRO SENSOR DRIVING CIRCUIT FOR DRIVING A VIBRATION TYPE GYRO SENSOR, A GYRO SENSOR SYSTEM, AND A GYRO SENSOR DRIVING METHOD

摘要

PURPOSE: A gyro sensor driving circuit, a gyro sensor system, and a gyro sensor driving method are provided to improve a signal processing capability as damages and advantages of a sensor are controlled by controlling a driving signal level.;CONSTITUTION: A gyro sensor driving circuit comprises a charge-voltage converting unit(110), a phase converting unit(120), a pulse generating unit, a pulse converting unit(140), and a control unit(170). The charge-voltage converting unit receives the charge output of a vibration type gyro sensor, thereby converting the same into voltage signals. The phase converting unit receives the signals from the charge-voltage converting unit, thereby converting phases. The pulse generating unit receives output signals of the phase converting unit, thereby outputting pulse waves. The pulse converting unit converts the pulse waves output by the pulse generating unit into pulse signals based on a specific voltage level for applying the pulse waves as driving signals.;COPYRIGHT KIPO 2013;[Reference numerals] (110) Charge-voltage converting unit; (120) Phase converting unit; (130) Comparator; (140) Pulse converting unit; (170) Control unit; (AA) Sensor output signal; (BB) Sensor input signal
