Response to the following problem:
The circuit in Figure is biased at VCC = 10 V and has a collector resistor of RC = 4 kΩ. The voltage VB B is adjusted such that VC = 4 V. The transistor has β = 100. The signal voltage between the base and emitter is vbe = 5 sin ωt(mV). Determine the total instantaneous values of iB(t), iC(t), and vC(t), and determine the small-signal voltage gain Av = vc(t)/vbe(t).
