Given a CE amplifier with an input current of 20 μA and a beta of 150, calculate the collector current I_C and verify its effect on transconductance g_m for an assumed V_T of 26 mV.
💡 Hint: Use the relationship between beta and collector current.
Design a multi-stage amplifier using both CE and CC configurations, and explain the effect of each configuration on gain and bandwidth in a summary report.
💡 Hint: Focus on the interactive role of both configurations in the cascading design.
