Consider an amplifier circuit using a BJT having I, = 1015 A, a collector resistance R = 6.8 k2, and a
power supply Vcc = 10 V.
(a) Determine the value of the bias voltage VE required to operate the transistor at Ve = 3.2 V. What is
the corresponding value of I?
(b) Find the voltage gain A, at this bias point. If an input sine-wave signal of 5-mV peak amplitude is
superimposed on VRg, find the amplitude of the output sine-wave signal (assume linear operation).
(c) Find the positive increment in v (above VaE) that drives the transistor to the edge of saturation,
СЕ
where
VCE
= 0.3 V.
(d) Find the negative increment in ver that drives the transistor to within 1% of cutoff (i.e., to
VCE = 0.99Vcc).
