  • CHAPTER 4. DIODE CIRCUITS794.4Problems1.(a) Make a sketch showing the current through an ideal diode as a function of theapplied voltage. Also sketch the current through a real signal diode as a functionof voltage.(b) Make a sketch showing the current drawn through a Zener diode as a functionof the applied voltage. Show how to determine the forward resistance (Rf ), thereverse resistance (Rr) and the Zener resistance (RZ) from your sketch. Label thevoltages VPN and VZ.2. Sketch the expected output waveforms when(a) a 100 Hz sine wave with a peak voltage of 5 V, and(b) a 100 Hz square wave with a peak-to-peak voltage of 10 Vare applied separately to each of the circuits below.6.3V5V3VDACB3. The Zener diode in the following circuit is characterized by VPN =0.6 V and|VZ| =4.8 V. Terminal B is at ground and there is no external load resistor.+13.2V10kohmBA
