I need to drive piezoelectric transducer having 1.6MHz resonant frequency, 30V max rating. I do lots of search on google and edaboard and coudn't find much useful information.
All I understand it needs a sinusoidal waveform , a kind of tuned amplifier with mosfet should be used. I really appriciate any information on the subject. Desparately looking for related books and web sites.
Actually, I have done a bit of study on piezoresistive transducer interface ckt recently. I am able to find lots of such circuit from IEEE and Biosensors & Bioelectonics.
For example,this paper "Cantilever-Based Biosensors in CMOS Technology", Proceedings of the Design, Automation and Test in Europe Conference and Exhibition (DATE’05), shows two interface ckt for the transducer. Hope that helps you.
