Abstract: A variable capacitance device that achieves a desired capacitance even when factors causing varied capacitances are generated is configured such that a capacitance detection pulse signal is applied from a capacitance detection signal generation unit to a driving capacitor and a reference capacitor of a MEMS mechanical unit. The device voltage of the driving capacitor based on the capacitance detection signal and a driving voltage is applied to the inverting input terminal of a comparator. The device voltage of the reference capacitor based on the capacitance detection signal and the driving voltage is applied to the non-inverting input terminal of the comparator. The comparator generates a comparison output signal including “Hi” and “Low” values from the difference between these device voltages, and applies the output signal to a driving voltage generation unit. The driving voltage generation unit increases or decreases the driving voltage based on the comparison output signal.
