In the circuit in the figure, Vcc = 18 V and RL = 2.2 ko, while C₁ = C₂ = CE = 0.1 µF. It is also known that for parasitic and wiring capacitors, Cwi = 15 pF, Cwo = 21 pF, Cbc = 27 pF, Cbe = 817 pF and Cce = 25 pF. Accordingly, what is the bandwidth of the system? NOTE-1: The output impedance of the transistor will be neglected in ro calculations. NOTE-2: The high frequency dependence of hfe, , will be neglected.
