EECS 70LB Spring 2011 Lab 4: Diode Circuits II Readings from Scherz: (In addition from Lab 3) 4.2.6 (Zener Diode); Summary: There are 3 circuits for this lab designated as 4-1, 4-2, 4-3 4-1 Waveform Modifier and Limiter using Zener Diodes (Fig. 4.32, pp 433, Scherz) Procedure: Construct the circuit as shown in Fig. 4-1. Use a 1N4733A Zener diode (V z of 5.1V) for Z 1 and a 1N4739A Zener diode (Vz of 9.1V) for Z 2 . Use a 10 kHz sinusoidal signal as the source. Vary the amplitude of the source from 4V to 10V continuously. Sketch the output waveform and write down the maximum and minimum voltages at amplitudes of 4, 6, 8, and 10 V). Fig. 4-1 Prelab report: Simulate the circuit responses using PSPICE. To simulate a zener diode, use the DBREAKZ model from the BREAKOUT library. You need to specify the breakdown parameters of the zener diode. Right-click on the zener diode after you’ve placed it, choose “Edit PSpice Model.” Add the following code to the model for the zener diode: For the 1N4733A: Bv=5.1 Ibv=49e-3 For the 1N4739A: Bv=9.1 Ibv=28e-3 where “Bv” is the zener breakdown voltage and “Ibv” is the zener breakdown current.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
