P-N Junction Diode
In the given circuit the input voltage Vin is shown in figure. The cut-in voltage of p-n junction diode (D1 or D2) is 0.6 V. Which of the following output voltage (V0) waveform across the diode is correct?
![]()
Show answer and solution
Answer: (d)
- and are in parallel with opposite orientation across the output.
- Positive half: one diode turns on once V, so is clipped at V.
- Negative half: the other diode turns on, so is clipped at V.
- Output follows the input up to V and is flat beyond it. So the answer is (d).
