Question : 23 of 65

Marks: +1, -0

In the figure, D1 is a real silicon p-n junction diode with a drop of 0.7 V under forward bias condition and D2 is a Zener diode with breakdown voltage of -6.8 V. The input V_in(t) is a periodic square wave of period T, whose one period is shown in the figure.

Assuming 10τ ≪ T, where τ is the time constant of the circuit, the maximum and minimum values of the output waveform are respectively,

7.5 V and -20.5 V
6.1 V and -21.9 V
7.5 V and -21.2 V
6.1 V and -22.6 V
