1. What is Output Voltage of BJT Amplifier?

The Output Voltage of a BJT Amplifier is the voltage level at the output terminal after amplification. It is calculated by subtracting the voltage drop across the load resistance from the supply voltage.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V_o \) — Output Voltage (V)
• \( V_{DD} \) — Supply Voltage (V)
• \( I_d \) — Drain Current (A)
• \( R_L \) — Load Resistance (Ω)

Explanation: The formula calculates the output voltage by subtracting the voltage drop across the load resistor from the supply voltage.

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 supply voltage in volts, drain current in amperes, and load resistance in ohms. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical range for output voltage?
A: The output voltage typically ranges from 0V to the supply voltage, depending on the circuit configuration and component values.

Q2: How does load resistance affect output voltage?
A: Higher load resistance results in a larger voltage drop, which decreases the output voltage for a given drain current.

Q3: What happens if drain current is too high?
A: Excessive drain current can lead to significant voltage drop across the load resistor, potentially reducing output voltage to undesirable levels.

Q4: Can output voltage be negative?
A: In this configuration, output voltage cannot be negative as it's derived from positive supply voltage minus a positive voltage drop.

Q5: How accurate is this calculation?
A: This calculation provides a theoretical value. Actual output voltage may vary due to component tolerances, temperature effects, and other circuit parameters.
