A diode with Is 5 2 fA, rS > 0, K 5 10216 A, and a 5 1 is forward-biased at ID 5 100 A by a 3.3-V supply via a series resistance R. The supply itself exhibits noise that can be assumed white with a density of ens 5 100 nV/ √ ___ Hz . (a) Combine ens, enr, and the effect of ind to fi nd the overall noise voltage en(f) across the diode, and express it in the form of Eq. (7.125). What are the values of enw and fce? (b) Repeat if R is changed so as to bias the diode at ID 5 1 mA.
