1. What is Output Voltage at Drain Q2?

The Output Voltage at Drain Q2 (V_O2) refers to the voltage measured at the drain terminal of transistor Q2 in a differential amplifier circuit. It is calculated based on the output resistance and total current flowing through the circuit.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V_{O2} = -(R_{out} \times I_t) \]

Where:

\( V_{O2} \) — Output Voltage at Drain Q2 (Volts)
\( R_{out} \) — Output Resistance (Ohms)
\( I_t \) — Total Current (Amperes)

Explanation: The negative sign indicates that the output voltage is inverted relative to the input signal in typical differential amplifier configurations.

3. Importance of Output Voltage Calculation

Details: Accurate calculation of output voltage is crucial for designing and analyzing differential amplifier circuits, ensuring proper signal amplification, and maintaining circuit stability in various electronic applications.

4. Using the Calculator

Tips: Enter output resistance in ohms (Ω) and total current in amperes (A). Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why is the output voltage negative in the formula?
A: The negative sign indicates phase inversion in common-source amplifier configurations, where the output signal is 180 degrees out of phase with the input signal.

Q2: What is the typical range for output resistance?
A: Output resistance values can vary widely depending on the specific MOSFET and circuit configuration, typically ranging from hundreds to thousands of ohms.

Q3: How does total current affect the output voltage?
A: The output voltage is directly proportional to the total current - higher current results in higher output voltage magnitude (though negative in sign).

Q4: Can this formula be used for other transistor types?
A: While the basic principle applies, specific parameters may differ for BJTs or other transistor types. This formula is specifically designed for MOSFET circuits.

Q5: What factors can affect output resistance?
A: Output resistance is influenced by MOSFET parameters such as channel length modulation, bias conditions, and the specific circuit configuration used.
