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.

First Hertz (Hz)

Required number input.

Second Hertz (Hz)

Required number input.

First Volts (V)

Required number input.

Second Volts (V)

Required number input.

Average VCO frequency tuning sensitivity between two measured voltage-frequency operating points. 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]

Hertz Per Volt (Hz/V)

The resulting hertz per volt returned as a number.

• VCO gain and tuning sensitivity are operating-point quantities that vary across tuning voltage, frequency, supply, temperature, load, and process. Phase noise, pushing, pulling, linearity, and tuning range require the device curves.
• 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.

• Battery Internal Impedance

  Estimate DC battery internal resistance from the voltage drop between two load-current operating points measured over a short interval.

• Audio Crossover Slope

  Find signed filter attenuation slope in dB per octave between two measured frequencies; nonlinear transitions need more points.

• GaN HEMT Rds On Tempco

  Calculate average GaN HEMT on-resistance temperature coefficient as percent change per Celsius degree between two measured temperatures; this is not a local derivative.
