Question 2

A p-n junction diode has a reverse saturation current rating of 50 nA at 32°C. Assuming at 32°C is 26 mV. The dynamic AC resistance of the diode at 32°C and forward voltage drop of 0.5 V

Question 3

Assuming diode are ideal in figure the current in diode D1 is Question 4

Determine the region of operation of silicon transistor shown in circuit below: [Assume: β = 150, VBE (sat) = 0.8 V, VBE (active) = 0.7 V, VCE (sat) = 0 V, VD for diodes D1 & D2 is 0.7 V]

Question 5
