Question

In the given circuit, the input voltage $V_{	ext {in }}$ is shown in figure. The cut-in voltage of $p-n$ junction diode ( $D_1$ or $D_2$ ) is 0.6 V . Which of the following output voltage $\left(V_0ight)$ waveform across the diode is correct?

Professor PC Thomas Classes · Answer

(d) : For the positive half cycle, diode $D_1$ is forward biased and diode $D_2$ is reverse biased. For the negative half cycle, diode $D_1$ is reverse biased and diode $D_2$ is forward biased. Till $|V| \leq 0.6 \mathrm{~V},\left|V_0\right|=|V|$.
