I am trying to drive a piezoelectric transducer with maximum power transfer possible with minimum possible noise. In order to do that I am trying to implement LC matching circuit such as circuit described in below picture.
Websites that calculates L and C values for me ask for source and load impedance. Load impedance is fixed by the characteristics of piezoelectric transducer. However, I have the liberty of choosing the value of source impedance as it is from a gate driver with output impedance smaller than 10 Ohms. I can add just a series resistor to create my source impedance.
My question is that, is there any guidelines for choosing the value of source resistance? I noticed that as I make it smaller and smaller, the power transfer at resonant frequency increases along with Q value.
