Response to the following problem:
Sketch the iC -vCE characteristics of an npn transistor having β = 100 and VA =100 V. Sketch characteristic curves for iB = 20 μA, 50 μA, 80 μA, and 100 μA. For the purpose of this sketch, assume that iC = β iB at vCE= 0. Also, sketch he load line obtained for VCC =10 V and RC =1 kΩ. If the dc bias current into the base is 50 μA, write the quation for the corresponding iC -vCE curve. Also, write the equation for the load line, and solve the two equations to obtain VCE and IC. If the input signal causes a sinusoidal signal of 30-μA peak amplitude to be superimposed on IB, find the corresponding signal components of iC and vCE.
