2 cards from this section. Quick, good the night before a test.
What is the primary advantage of using a differential amplifier?
Think about why it's called 'differential'.
What does BJT stand for?
What type of charge carriers does it use?
What is the function of an active tail resistor in a differential amplifier?
Think about what stability means in regards to current flow.
True or False: BJTs can only be used in high-speed applications.
Consider the characteristics of BJTs.
A differential amplifier has a base bias of 12V with a BJT configured. If the base resistor is 570 kΩ, calculate the emitter current if V_BE = 0.6V.
Use Ohm's law to find current from voltage and resistance.
Discuss the impact of a weak common mode rejection ratio in a sensitive amplifier application. What strategies would you employ to mitigate common mode signals?
Think of ways you can enhance signal clarity in your designs.
