Question 1
Given a CE amplifier with an input current of 20 ΞΌA 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.
π‘ Hint: Use the relationship between beta and collector current.
Question 2
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.
π‘ Hint: Focus on the interactive role of both configurations in the cascading design.
