Question

4.

i) The terminal voltage to ground are measured on a particular BJT. In what region does the device operate if these terminal voltages are equal to the following values? VC=6V, VB=2V, VE =1.3V

ii) The currents iB= 20 µA and iC = 4mA flow in the particular BJT that operates in the constant current region.

(1) What is the value of bf for this device?

(2) What iB will be required to set iC = 20mA?
