2 cards from this section. Quick, good the night before a test.
What is the purpose of using active loads in amplifiers?
Think about the benefits of active elements compared to passive ones.
Define collector current.
Consider what defines the behavior of a transistor in a circuit.
What is the primary benefit of using an active load over a passive load in amplifiers?
Think about what characteristics define the performance advantage.
True or False: The collector current in a transistor should always be equalized in multi-transistor configurations to avoid distortion.
Consider the implications of imbalance in electrical signals.
Design an amplifier circuit utilizing an active load. Ensure the operating points achieve I_C = 2 mA and V_CE centered at 6 V. Discuss how the choice of resistors and transistors would affect performance.
Recall the relationships between base current, collector current, and how resistor values determine these currents.
If an active loaded CE amplifier reaches a voltage gain of 1000, compute the input and output resistances, taking into account parasitic capacitances affecting performance.
Review the small signal analysis concepts discussed earlier to manage variations.
