Model voltage controlled oscillators with flexible calibration inputs. Generate tables, curves, and downloadable result reports. Check linear behavior across ranges using practical engineering assumptions.
This sample uses a linear sensitivity of 2000 Hz per volt with a 1000 Hz intercept.
| Voltage (V) | Frequency (Hz) |
|---|---|
| 0.0 | 1000 |
| 1.0 | 3000 |
| 2.0 | 5000 |
| 3.0 | 7000 |
| 4.0 | 9000 |
| 5.0 | 11000 |
Voltage to frequency conversion often follows a linear voltage controlled oscillator model. The direct form is:
f = fref + K × (Vin - Vref)
Here, f is the output frequency, fref is the known reference frequency, K is sensitivity in frequency per volt, and Vin is the applied voltage.
When two measured operating points are available, this page also calibrates the line with:
m = (f2 - f1) / (V2 - V1)
f = mV + b
For reverse design, required voltage can be solved from:
V = Vref + (ftarget - fref) / K
This layout is useful for oscillator tuning, control system prototyping, lab verification, and signal conditioning studies where voltage controlled frequency behavior must be estimated quickly.
It estimates oscillator output frequency from an applied control voltage using a linear relationship or a calibration line built from measured points.
A linear model works when the device operates inside a region where frequency changes approximately proportionally with voltage. Always compare with measured data.
Sensitivity expresses how much frequency changes for each volt of control input. It is the slope of the voltage frequency response line.
Yes. The calibration mode computes slope and intercept from two known voltage frequency pairs, then predicts frequency anywhere on that line.
Use the reverse mode. It rearranges the linear equation and returns the required control voltage for the requested frequency target.
They let you enter or display values in convenient engineering units without changing the underlying calculation method.
The graph plots the computed voltage frequency response across your selected voltage range and highlights the evaluated operating point when available.
Yes. They help document assumptions, share generated tables, and keep a record of design calculations for reports or test notes.
