Unformatted text preview: 1 ECE2280 Homework #3 Solution Spring 2010 1. Assume all diodes are identical and have V DO =0.7V, n=1, and V T =25mV. Use the constant voltage drop method. Verify that your assumption for the diode operation(i.e. on or off) are correct. Find the following making sure you find the correct operation of the diodes. a) State your assumptions (diode is on/off). b) The current I D1 c) The current I D2 d) The voltage Vo e) Your verification to prove your assumptions for the diodes are correct. f) If there is noise on the 2V supply of ± 1V, what is the total value for I D1 (the AC current through diode, D1). {Hint: remember to use the AC model for the diode} + _ +10V 1 mA D1 D2 2V 630 Ω 100 Ω 20 Ω D1 I D2 I10V o V  1V + 2 2.
