Equivalent Circuit
The following electric circuit can be used to model a resonance / anti-resonance pair that exists in the electrical impedance of piezoelectrics.
Equivalent Circuit
The following 2 conditions are required for the circuit to accurately simulate piezoelectric resonance behavior:
The value of C must be much smaller than Cp
C and Cp in parallel must equal the piezo's low-frequency capacitance
The frequencies (in Hz) of the electrical resonance and anti-resonance are given by the following equations (which assume a small series resistance R):
