(a) A student is using a constant current source IS 5 1 mA to forward bias a diode D1 having nVT 5 50 mV. What is the diode’s dynamic resistance rd? (b) If a second identical diode D2 is connected in parallel with D1, what are the dynamic resistances of the individual diodes as well as the overall dynamic resistance of the two-diode structure? (c) If a third identical diode D3 is connected in series with the parallel structure of part (b), what are the individual dynamic resistances as well as the overall dynamic resistance of the three-diode structure? Again, comment.
