3 cards from this section. Quick, good the night before a test.
What is the key advantage of using an active load?
Think about how resistance affects gain.
Define 'Output Voltage'.
Recall the relationship between input and output.
What is a key property of common source amplifiers?
Consider the purpose of using active components.
True or False: The output resistance in a common source amplifier is significantly lower than in a common emitter amplifier.
Think about the effect of loading on resistance.
In a MOSFET CS amplifier, the supply voltage is 15V, V_GS = 1.5V, and the transconductance is 5 mS. Calculate the expected output voltage if the load resistor is 4 kΩ.
Break down the formula into parts—find the conductivity effect first!
A circuit has two different transistors with β values of 150 and 200. How will you adjust the base currents to ensure they reach the same collector current?
Apply the relationships of current and beta for stability.
