n a common-source JFET amplifier, the output voltage is _____________?
Correct answer: A. 180o out of phase with the input
- A. 180o out of phase with the input
- B. in phase with the input
- C. 90o out of phase with the input
- D. taken at the source
Explanation
In a common-source amplifier, an increase in drain current produces a larger voltage drop across the drain resistor, making the drain voltage fall. Therefore the output is 180° out of phase with the input.
