Simplest Piezo Driver Circuit Explained


Posted on Feb 5, 2014

In the previous post we discussed a piezo transducer element and learned how to use it with electronic circuits. In this article we will see how a piezo tranducer can be driven or operated using a simple circuit. However the amplification procedure is not by using conventional amplifying circuits as used in systems incorporating speakers, but rath

er it is simply implemented through an inexpensive inductor. The low power frequency which may be available from a relevant circuit or an IC is first amplified using a transistor, and further more the transistor output is pumped up using an inductor. The use of a inductor becomes the most crucial stage for driving a piezo electric transducer.
