+ 17: There are two questions, first about an ideal diode and then about a modeled diode. For the modeled diode, the voltage across its terminals is 0.7V when it is "on". Which of the following statements are true about the ideal diode above? a. If i= 0, then v≤ 0. b. If v = 0, then the diode might be replaced by a short circuit or an open circuit. c. If i > 0, then the diode can be replaced by a dependent voltage source. d. It is impossible for v to be equal to 0. e. If v<0, then the diode can be replaced by a open circuit. f. If v<0, then i = 0. g. None of these statements is true. Enter a single string of letters, in alphabetical order ("abcdef"). Answer: Which of the following statements are true about the modeled diode above? a. If v<0, then the diode can be replaced by an independent current source. b. If v=0.7V, then the diode can be replaced by an independent voltage source. c. If i> 0, then v > 0. d. If v < 0.7V, then the diode can be replaced by a open circuit. e. If v = 0, then the diode can be replaced by a short circuit. f. If v<0, then i > 0. g. None of these statements is true. Enter a single string of letters, in alphabetical order ("abcdef"). Answer:

Please show all work, thank you :)

For the diode circuit to the right 8002 a V 1002 b 40mA 0.001V' a) To the left of points a and b, find the load-line relation by expressing the current, I with voltage, V. HINT: Write KCL equation for the circuit diagram and write I in terms of V from that KCL equation. This will be your load-line equation. b) Assume the diode has the following characteristic, using the load-line relation you found in (a), determine the operating voltage, V and current, I for the circuit. ip (mA) 20 15 10 5 Vp (V) 3.0 0.5 '1.0 1.5 2.0 2.5

Vi (t) = 10.sinwt Does not pass positive alternans when Volt input voltage is applied, only Design and explain two different circuits that pass negative alternans. Draw the input and output voltages. What are the types of these circuits? (Note: You can use the ideal diode approach)
