1. What is the Output Voltage Formula?

The output voltage formula \( V_{out} = V_s - (I_d \times R_L) \) calculates the output voltage of a MOSFET amplifier by subtracting the voltage drop across the load resistance from the source voltage.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V_{out} \) — Output Voltage (Volt)
• \( V_s \) — Source Voltage (Volt)
• \( I_d \) — Drain Current (Ampere)
• \( R_L \) — Load Resistance (Ohm)

Explanation: The formula calculates the output voltage by accounting for the voltage drop across the load resistance due to the drain current flowing through it.

3. Importance of Output Voltage Calculation

Details: Accurate output voltage calculation is crucial for designing and analyzing amplifier circuits, ensuring proper signal amplification, and maintaining circuit stability.

4. Using the Calculator

Tips: Enter source voltage in volts, drain current in amperes, and load resistance in ohms. All values must be non-negative.

5. Frequently Asked Questions (FAQ)

Q1: What is the significance of output voltage in amplifiers?
A: Output voltage determines the amplified signal strength and is critical for proper circuit operation and signal integrity.

Q2: How does load resistance affect output voltage?
