1. Find the Q-point values. 2. Draw the AC equivalent circuit a. Calculate the input and output resistances of both stages b. Solve for the gain of the common source (CS) when isolated (C2 is open) from the common drain (CD) circuit. Let lambda = 0. c. Solve for the gain of the CS when connected to the CD amplifier. Let lambda = 0. 3. What does this tell you about ideal input and output resistances?/nThe Lab C1 HH 10uF FunctionGen V2 -6 V R1 383kQ V1 6 V Rd 16kQ Cc2 BS170 HH R2 135kQ Rs1 4ΚΩ HA Figure 1: Circuit Diagram.
