A common-emitter amplifier with an external capacitor CC connected across the base and the collector of the transistor is shown in Fig.
Transistor data gm = 5mA/V, $${r_\pi }\, = \,200K\Omega, $$ $${C_\pi }\, = \,1.5$$ pF and $$C\mu \, = \,0.5$$ pF determine the upper cutoff frequency fH of the amplifier
