Document Summary
Ee 105 midterm 1: pn junction capacitor (18 pts) Hint: you can assume that the doping concentration on the p-side is much greater than either n(d1) or n(d2).

Ee 105 midterm 1: sketch the electric field on the graph below for the case when the depletion region edge has just reached w2. Your plot should show the relative magnitudes of n(d1) and n(d2) correctly; note that n(a) >> n(d1) and n(d2). (3 pts: the area of this pn junction capacitor is 100 micrometers^2. The units for the current should be na(10^-9 a). (3 pts: if the applied voltage is v(d)(t) = v(d) + v(d)(t) = -9v + *v(d)cos(omega*t), What is the maximum amplitude *v(d) for which the current into the pn junction capacitor is exactly proportional to dv(d)/dt? (3 pts: integrated circuit resistor (20 pts) file:///c|/documents%20and%20settings/jason%20raf0105%20-%20spring%202000%20-%20howe%20-%20mt1. htm (2 of 5)1/27/2007 4:32:20 pm.
