The values of Q1. Figure 1 shows a BJT amplifier whose voltage gain the components are shown in the figure. a) Identify the capacitors in Figure 1, whose influences are negligible when considering the frequency response over high frequency range of > 1 MHz. Explain briefly the reason. b) Draw the small signal equivalent circuit of Figure 1, which is used for analysing the frequency response over the high frequency range. c) Identify the capacitor that needs treatment using the principle of "Miller effect capacitance". Calculate the input and output Miller capacitances.
