For DC operating point
set vin=0
then
KVL at input loop
this can be written as
substituting the given values
this equation is a equation of line .graph it on the input characteristics given
At vBE=0 Ib=20uA, at iB=0, vBE=VBB=1.2V
therefore, the operating point is
Now, KVL at output gives
therefore
substituting the given values
graph this line on output characteristics
therefore, the operating point is
Ic=5mA
Vce=10V
b)
c)
FRom output graph
Vce(sat)=~1
therefore
similarly
4)
therefore

Download the datasheet for 2N3904 and find the value of Bp. (Hint: Use average value) Be= Voc +10 V RB We are going to consider the common emitter configuration circuit shown in the figure to test a 2N3904 npn Bipolar Junction Transistor (BJT) under DC bias conditions. Your circuit should place a fixed collector resistor, Rc, in the circuit to prevent the collector current, Ic, from exceeding 40 mA (for this, you know that the minimum value of is zero)....
