tracking resonance
tracking resonance
(OP)
I have a small tube/pzt transducer assembly that I want to put into resonance and lock in on a particular mode so that when changes in ambient occur the assembly will stay in that resonant mode. The mode occurs at ~2Mhz. Is there some kind of simple impedance analyzer/RF amp/phase locked loop-on-a-chip that would handle this task?






RE: tracking resonance
There are usually two resonant modes; seies and parallel and you may need to decide which one you shall be running in. Different amplifier and feedback topologies give you either p or s resonance.
