2 cards from this section. Quick, good the night before a test.
What is an active load?
Think about how load affects amplifier performance.
Why is it beneficial to match β values in BJTs?
Consider how current impacts overall circuit behavior.
What is the primary purpose of using active loads in amplifiers?
Consider how load type affects the gain.
True or False: The collector current of both transistors in an active load design should be unequal to maintain performance.
Remember the importance of balance in multi-transistor configurations.
Given a circuit diagram of a CE amplifier, analyze the impact of varying the active load resistance on voltage gain and output impedance.
Consider the relationships established in previous exercises about load resistance.
Determine the effects on the amplifier’s performance if one BJT has a significantly lower beta than its counterpart when both are configured with an active load.
Think about how effective biasing could mitigate the issue.
