2 cards from this section. Quick, good the night before a test.
What is the purpose of biasing a common source amplifier?
Think about the transistor's operation regions.
What is the typical configuration of a common source amplifier?
Recall the basic setup of a common source circuit.
What is the purpose of choosing the correct resistor values in a common source amplifier?
Consider what affects an amplifier's performance.
True or False: The DC operating point should be set at extremes of the output voltage range.
Revisit how swings impact voltage selection.
Design a common source amplifier for a given target of 1 mA drain current. Use a supply voltage of 15V. Determine the resistor values for R1, R2, and R_D by applying design principles discussed.
Remember to maintain resistor ratios to achieve the desired gate voltage.
If increasing V_th from 1V to 2V affects the output swing, what practical differences would you need to address in your design?
Investigate how threshold voltage is tied to your operating point.
