AI Overview
Frequency to voltage (F/V) conversion
transforms an input signal's frequency into a proportional DC voltage
, commonly achieved using specialized ICs (e.g., LM2907, TC9400), Phase-Locked Loops (PLLs), or charge-pump circuits. The method generally involves converting the input into narrow, fixed-duration pulses, which are then integrated or averaged to generate a smooth, linear output voltage.
Key Frequency to Voltage Conversion Methods
- Charge-Pump/Averaging Method (e.g., LM2907): Input pulses charge a capacitor ( ) to a set level, which then discharges into a low-pass filter (integrator) circuit during every cycle, producing a DC voltage proportional to frequency ( ).
