Use this electronics calculation for a first-pass component, converter, signal, motor, or sensor estimate when the stated operating conditions and units match the device data.

Resonance frequency (Hz)

Required number input.

Lower half-power frequency (Hz)

Required number input.

Upper half-power frequency (Hz)

Required number input.

Calculate a MEMS resonance quality factor from peak frequency and the two measured half-power frequencies. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Resonance quality factor

The resulting resonance quality factor returned as a number.

• MEMS resonance, scale factor, and Q depend on structure, packaging pressure, temperature, drive amplitude, damping, fabrication spread, mounting stress, and readout electronics. Lumped models may not capture mode coupling or nonlinear operation.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check the result against the current datasheet and worst-case operating corners, then verify the circuit or measurement with simulation and bench testing where failure matters.

• Audio Equalizer Q

  Calculate equalizer center-frequency Q from measured lower and upper half-power frequencies.

• Bandwidth From Q

  Calculate the bandwidth of a resonant circuit from its resonant frequency and quality factor.

• Crystal Quality Factor

  Calculate a crystal motional branch's unloaded series Q from series frequency, motional inductance, and series resistance.
