Answers for tutorial 2:

Note: Vt = kT/q is assumed to be 26 mV for these answers.

1. 38.5 uA.
2. If Vd is the voltage across the series combination of the two diodes, Vt is kT/q, then:
   Id = sqrt(I_S1 I_S2) exp(Vd/(2Vt)).
3. A 50 Hz, 5 V amplitude source is to be used. The full wave bridge rectifier should have a load resistance of 6.5 Ohm, with a capacitor in shunt with the load. The cap should be at least 1.4 mF.
4. At steady state, output will be a constant voltage of 2V_in. (V_in was the amplitude of the input sinusoid.)
5. 0.25 mA.
