voltage frequency converter (VFC)

A Voltage Frequency Converter

(VFC) is an electronic circuit that converts a voltage into a frequency. In such a circuit, there is a direct, partially linear relationship between the voltage level (U) at the circuit input and the frequency (f) at the circuit output: U/f. Voltage-to-frequency converters can be implemented by A/D converters using the voltage-to-frequency method, by multivibrators, or by a voltage-controlled oscillator

(VCO), but they differ in circuit construction.

Voltage-frequency converters consist of the three circuit blocks inverter, integrator and Schmitt trigger. They are functionally comparable to inverters and are also used in them.
