[Claims for Utility Model Registration] A digital servo circuit that receives a rotation detection signal of a rotating body and derives a rotation control signal as a PWM wave; a first low-pass filter that smoothes the rotation control signal; a differential amplifier connected to an output terminal of the low-pass filter and the other connected to a reference voltage terminal, which generates a control signal for a motor that drives the rotating body; and a reference signal oscillation circuit built into the digital servo circuit. A servo device comprising: a frequency dividing circuit that divides the output of the reference oscillation circuit at a fixed period to create a reference pulse signal; and a second frequency dividing circuit that smoothes the reference pulse signal and outputs it to the reference voltage terminal. A servo device comprising: a low-pass filter.
