Abstract
A displacement converting device converts mechanical movement of a sensor or actuator mechanisms to a corresponding electrical signal by varying the electrostatic capacitance of one or a combination of capacitors in accordance with the mechanical movement. Current generating circuits produce currents having magnitudes corresponding to the capacitance values. An operational amplifier generates an output signal having a value corresponding to the mechanical movement by comparing the magnitudes of the generated currents.
