2 cards from this section. Quick, good the night before a test.
What's the purpose of determining the DC operating point in amplifier design?
Think about what happens if the point is too high or too low.
Define saturation in the context of a transistor's operation.
Consider how this affects the transistor's ability to amplify.
What is the main goal of setting the DC operating point in amplifier design?
Consider the implications of adjusting this point in terms of swing.
True or False: The gain of a common source amplifier depends on both transconductance and load resistance.
Recall how gain is formulated.
Determine the values of R1 and R2 given that the desired gate voltage is 2V from a 15V supply and current is 1 mA. Note the threshold voltage is 1V. Show all work.
Remember to outline the impact of V_th on your calculations.
If the threshold voltage of a transistor is 1.5V and you need the output swing of 5V with a supply voltage of 10V, what should the target DC voltage at the drain node be? Calculate and explain how to achieve this.
Consider how the output swing relates directly to the drain voltage.
