4 cards from this section. Quick, good the night before a test.
Define the term 'Q-point' in the context of BJT circuits.
Think about where the transistor operates most efficiently.
What is a small signal equivalent circuit?
Consider how we deal with tiny changes in input.
What is the purpose of linearization in analog circuits?
Why would we want to make something simpler in engineering?
The Q-point is...
Think of where a device functions best.
Design a circuit that incorporates a BJT and specify how you would find and justify your Q-point. Include calculations for your expected input and output voltages.
Consider the relationship between input currents and output currents, especially focusing on finding the bias point within the linear range.
Given a linearized BJT circuit model, if the input voltage increases by 0.05V and the gain is measured at 50, calculate the expected output voltage change.
Use the relationship between input and output to express the changes simply.
