Abstract
An angular velocity signal detection circuit includes: a first current-voltage conversion circuit that converts, into a voltage, a current outputted from a first detection electrode of a gyroscope, and amplifies the voltage, thereby outputs a first conversion signal; a second current-voltage conversion circuit that converts, into a voltage, a current outputted from a second detection electrode of the gyroscope, and amplifies the voltage, thereby outputs a second conversion signal; an arithmetic operation unit that performs arithmetic operations by using the first conversion signal and the second conversion signal, and outputs a first processing signal and a second processing signal; and a third difference arithmetic operation circuit that amplifies a difference between the first processing signal and the second processing signal.
