4 cards from this section. Quick, good the night before a test.
What is an active load in an amplifier circuit?
Think about how it differs from a passive load.
Explain what voltage gain means.
Consider how you measure this in dB.
What does the gain-bandwidth product indicate?
Think about how increasing one affects the other.
True or false: An active load can help prevent distortion in an amplifier.
Remember the role of an active load.
Design a simple circuit that maximizes voltage gain while ensuring that the signal swing stays within ±0.5V of the DC output voltage given a supply of 12V.
Begin by calculating the expected output range based on the given supply voltage.
Evaluate how variations in collector current affect the effective gain in an amplifier with active loads.
Refer to the small signal parameters previously established.
