摘要：
An angular rate sensor driving circuit shortens a start-up time without increasing a maximum level of amplification factor of a variable gain amplifier beyond a predetermined degree An output signal of a first amplifier is input to a positive input terminal of a third amplifier, a first resistor is inserted between a negative input terminal of the third amplifier and an output terminal of the third amplifier, a voltage having a potential in the vicinity of ½ of a power supply voltage is impressed on the negative input terminal of the third amplifier through a capacitor, a second resistor and a switch are connected in series between the output terminal of the third amplifier and an input terminal of a second amplifier, and the switch is activated by an output of a level judgement circuit.
