The present invention relates to a piezoelectric circuit, a piezoelectric driving circuit driving the piezoelectric circuit, and a driving method of the piezoelectric circuit. The piezoelectric circuit includes a sub-piezoelectric circuit, and an external inductor connected to the sub-piezoelectric circuit in parallel, and when a polarity of a piezoelectric voltage, that is, a both-end voltage of the piezoelectric circuit is inverted, the external inductor discharges the sub-piezoelectric circuit. The piezoelectric driving circuit comprises a full-bridge circuit including a first switch and a third switch that are connected to a first node of the piezoelectric circuit, and a second switch and a fourth switch that are connected to a second node of the piezoelectric circuit. |
