Questions 1. For the circuit shown below in figure 1, you are given: V DD = 5V and R = 1.67 k . The number of diodes wired in parallel is M . All diodes in the circuit are identical, and have the following parameters: I S = 10 -15 A and n=1.25 . Use the exponential model for each diode. Find the magnitudes of I, V 1 , V 2 and the number of diodes that need to be wired in parallel (i.e. find M) such that the output voltage is 1.657 V. 2. For the circuit shown below in figure 2, use the constant-voltage-drop model. Determine V out , and the current flowing through each diode. Clearly state all of your assumptions, and justify them. Hint: D1 and D4 are both ON.

3. Consider the circuit below. All diodes are identical . The two capacitors (infinite capacitance) are used to couple the input signal source to the diode circuit, and to couple the output of the diode circuit to the load resistor. They have no effect on signal analysis, but completely block DC current. Figure 3
