Pls answer the following. Thank you
Based on the amplifier given in Fig. 2, draw the small signal equivalent and derive the two time constants associated with capacitances C1 and C2. Assume early voltage is infinity. Finally, indicate which formula out of the two should be used for the lower 3 dB frequency calculation? Formulate the maximum gain. I need help solving this problem. I asked a similar question before but after trying to get some clarification on my values and my instructor said that it was incorrect. The values that I have attached as screenshots. Is there something wrong with the math. The main issue that came up is the value for the time constant for C1.
