All the parasitic capacitances in the Common Base (C.B.) stage of a Bipolar Junction Transistor (B.J.T.) do not significantly affect the frequency response. This is because in the C.B. configuration, the input signal is applied to the emitter, and the output is taken from the collector, with the base grounded. This configuration inherently offers a low input impedance and a wide bandwidth, making it less sensitive to the effects of parasitic capacitances compared to other configurations like Common Emitter (C.E.) or Common Collector (C.C.).
