●●● moodle.concordia.ca Consider a diode circuit, shown in Fig. 4, at room temperature. The diode displays a forward voltage of 0.7 V at a current of 1mA. The current ip is 11 mA with a given In and a resistance R that is adjusted to make iR = 0.5 IIN. a) Find vo in the case described above. b) Now, if the resistance R is reduced by 10% and I remains the same, find Avo, the voltage variation at the output, using the small signal model.
