EE 438 Homework #3 Analytical Diode Model 1. Text problem 3.18. 2. Text problem 3.19 3. Text problem 3.29 In the following problems the Multisim simulator is to be used to make measurements on commercial diodes in order to determine the values of the parameters I s and n that appear in the analytical models of the diodes. To perform the measurements connect a DC Current Source across the diode in the manner shown in the figure below. DC Current Source v D + _ i D It is necessary to make two different measurements on each diode in order to determine the two unknown parameters I s and n . Each of the two measurements will be made at a different value of current. The two current values are indicated for each problem. The DC

Unformatted text preview: current is set by double clicking on the symbol for the Current Source and then entering the desired current value in the popup window. The voltage, , is measured for each value of current with a Multimeter connected across the diode. In determining I D v s and n use q kT V T = ., where k = 1.38x10-23 , T = 300, and q = 1.6x10-19 . 4. Determine I s and n for the small signal diode 1N4148. Use the currents and . A 10 1 = D i A 100 2 = D i 5. Determine I s and n for the general purpose diode 1N4001GP. Use the currents and A 100 1 = D i mA 1 2 = D i 6. Determine I s and n for the power diode RGP30A. Use the currents and mA 1 1 = D i mA 10 2 = D i...
