Determine Vo1 and Vo2 for the networks of Fig. 2.159.FIG. 2.159

The silicon (Si) diode voltage is 0.7 V

The silicon diode is forward biased and is in the ON state.

Apply Kirchhoff's voltage law for loop 1 , to obtain the v_o1.

v_o1 =12 V-0.7 V 

=11.3 V

The Gallium Arsenide (GaAs) diode voltage is \(1.2 \mathrm{~V}\) Apply Kirchhoff's voltage law for loop 2 , to obtain the \(v_{o 2}\). \(v_{o 2}=1.2 \mathrm{~V}\)

(b)

Draw the circuit diagram:

Figure 2

The silicon (Si) diode voltage is \(0.7 \mathrm{~V}\)

The Germanium (Ge) diode voltage is \(0.3 \mathrm{~V}\)

Here, the Germanium (Ge) diode is in reverse biased state so it is in the OFF state.

Apply Kirchhoff's voltage law for loop 1 , to obtain the \(v_{o 1}\). \(v_{o 1}=0 \mathrm{~V}\)

Here, the silicon (Si) diode is in reverse biased state so it is in the OFF state.

Apply Kirchhoff's voltage law for loop 2 , to obtain the \(v_{o 2}\). \(v_{o 2}=0 \mathrm{~V}\)
