Question: Given the typical values of hie = 1 kΩ, hre = 2 x 10-4 and Av = -160 for the input configuration of Fig. 5.182:
Given the typical values of hie = 1 kΩ, hre = 2 x 10-4 and Av = -160 for the input configuration of Fig. 5.182:
a. Determine Vo in terms of Vi
b. Calculate Ib in terms of Vi
c. Calculate Ib if hre Vo is ignored.
d. Determine the percentage difference in Ib using the following equation:
-1.png){kind=small}
e. Is it a valid approach to ignore the effects of hre. Vo for the typical values employed in this example?
