Video Solutions for GATE 2001 ECE : Five Mark Questions ( Electron Devices )

1. For the circuit shown in figure, D1 and D2 are identical diodes 

    with ideality factor of unity. The thermal voltage VT = 25mV. 

 (a) If the reverse saturation current, I_S, for the diode is 1pA, then 

      compute the current I through the circuit.

 (b) Calculate V_F and V_r.
