摘要： A physical quantity sensor system drives a physical quantity sensor and detects a physical quantity signal from a sensor signal. An analog-to-digital conversion circuit respectively converts a monitor signal and the sensor signal to a digital monitor signal and a digital sensor signal. A drive control circuit controls a drive signal according to the digital monitor signal. A phase adjustment circuit adjusts the phase difference between the digital monitor signal and the digital sensor signal. A detection circuit detects the physical quantity signal by multiplying the digital monitor signal by the digital sensor signal after the phase difference adjustment by the phase adjustment circuit.

摘要： An amplitude detection circuit detects the amplitude value of a monitor signal responsive to self-excited vibration of a physical quantity sensor. A waveform shaping circuit converts the monitor signal to a pulse signal. A pulse amplitude modulation circuit adjusts the amplitude of the pulse signal according to the amplitude value obtained by the amplitude detection circuit and outputs the result as a drive signal for control of the self-excited vibration of the physical quantity sensor.

摘要： A switched capacitor has a differential amplifier and a sampling capacitance and a feedback capacitance at least one of which has a variable capacitance value, and is switchable between a first drive mode of amplifying an input signal with a positive gain responsive to the capacitance ratio of the sampling capacitance to the feedback capacitance and a second drive mode of amplifying the input signal with a negative gain responsive to the capacitance ratio. A control circuit changes the capacitance ratio, and also changes the drive mode of the switched capacitor, at predetermined timing.

摘要： A defect detection circuit capable of accurately detecting a defect existing in correspondence with a time period in which the operation of an optical disk unit is changed from recording operation to reproducing operation or from reproducing operation to recording operation. When the operation of the optical disk unit is changed, a mono-multi circuit outputs a signal MM1 for turning on the switch in an integration circuit to reduce the time constant of the integration circuit. A logic circuit is supplied with a defect detection circuit DD output from a comparator and the output signal MM1 from the mono-multi circuit, executes a computation to make ineffective the signal MM1 during a time period during which the defect detection signal DD indicates the existence of a defect, and outputs a signal CP to the switch in the integration circuit.
