2 cards from this section. Quick, good the night before a test.
What is an active load in amplifier circuits?
Think of how a transistor can dynamically adjust compared to a resistor.
Define voltage gain.
This is often expressed logarithmically.
What is a defining feature of an active load?
Think about the role of components in boosting performance.
True or False: The use of active loads in amplifiers helps increase power dissipation.
Reflect on how active components function compared to passive ones.
Given an amplifier's passive load configuration, calculate the expected voltage gain and then redesign it with an active load approach to improve gain by at least 50%. Show the calculations.
Use the formula for voltage gain but consider the variable nature of the active load.
Discuss in detail how changing one parameter in a common emitter amplifier configuration can vastly alter its performance. Provide examples.
Think about the operational characteristics and their relationships.
