Title: Driver for piezoelectric element
Inventor: NAKAMURA KAZUTO
IPC: H01L41/09
Filed: 1992-09-18
Abstract: PURPOSE:To allow stabilized charge control of a piezoelectric element with excellent linearity. CONSTITUTION:AC voltage VAC of an oscillator 26 is superposed on a DC drive voltage and applied on a piezoelectric element 1. A current detector 24 detects current IAC flowing through the piezoelectric element 1 and delivers the value of detected current to a divider 22. The divider 22 outputs a quotient V*=Q*/ IAC of the target value Q* of charge of the piezoelectric element l and the current IAC. A DC voltage KaV* amplified through a DC amplifier 23 is applied on the piezoelectric element 1 to induce charges Qp=Cp(KaV*) therein. Qp=Q* can be satisfied by selecting the amplification factor Ka of the DC amplifier 23 appropriately thus enabling charge control of the piezoelectric element 1.
