Ctri Question 3 (20 Marks) Lab 1-Zener Circuits and Applications Theory: Zener diode is designed to operate in reverse conduction. Zener breakdown occurs at a precisely defined voltage, allowing the diode to be used as a voltage reference or clipper. While Zener diodes are usually operated in reverse conduction, they may also be operated in cutoff and forward conduction. There are two different effects that are used in "Zener diodes". The only practical difference is that the two types have...

Please solve part d in MATLAB Problem Statement Consider the Shockley diode equation, which approximates the current-voltage (characteristic) curve of a diode: Here, is the current flowing through the diode (in amperes), and Vo is the voltage drop across the diode (in volts). VT is the thermal voltage, which varies based on the temperature. Assume that VT0.026 V, which is true when the diode is a little above room temperature. Therefore, in this equation, there are two unknown parameters that...
