1. What Is Phase Detector Average Voltage?

Phase Detector Average Voltage is the averaging of all the instantaneous values along the time axis with time being one full period, (T). It represents the output voltage of a phase detector circuit.

2. How Does The Calculator Work?

The calculator uses the formula:

Where:

• \( K_{pd} \) — Phase Detector Average Voltage (V)
• \( i_{pd} \) — XOR Phase Detector Current (A)
• \( \Phi_{err} \) — XOR Phase Detector Phase (rad)

Explanation: This formula calculates the average voltage output of a phase detector by dividing the detector current by the phase difference.

3. Importance Of Phase Detector Calculation

Details: Accurate phase detector voltage calculation is crucial for phase-locked loop (PLL) systems, frequency synthesis, and signal processing applications where precise phase detection is required.

4. Using The Calculator

Tips: Enter phase detector current in amperes (A) and phase difference in radians (rad). Both values must be positive and non-zero.

5. Frequently Asked Questions (FAQ)

Q1: What is a phase detector?
A: A phase detector is a frequency mixer or analog multiplier that generates a voltage signal representing the phase difference between two input signals.

Q2: What are typical values for phase detector current?
A: Phase detector current typically ranges from microamperes to milliamperes, depending on the specific circuit design and application.

Q3: Why is phase measured in radians?
A: Radians are the natural unit for angular measurement in mathematical calculations involving trigonometric functions and phase relationships.

Q4: What applications use phase detectors?
A: Phase detectors are used in PLL circuits, frequency synthesizers, demodulators, motor control systems, and communication systems.

Q5: How accurate is this calculation?
A: The calculation provides theoretical values based on ideal conditions. Actual circuit performance may vary due to component tolerances, noise, and other real-world factors.
