2 cards from this section. Quick, good the night before a test.
What voltage biasing condition applies to the base-emitter junction of an n-p-n transistor?
Think about how the voltage must flow for the junction to allow current.
What is the relationship between collector current and base current in a transistor?
Consider what β represents in context.
What condition must be met for the base-emitter junction of an n-p-n transistor to function properly?
Think about the flow of current through the junction.
In a p-n-p transistor, how is the emitter related to the base in terms of voltage?
Recall the conditions for forward biasing.
Design a p-n-p transistor circuit that can amplify an input signal of 5 mV. Identify necessary component values and biasing.
Use the relationships between input and output voltages and the properties of p-n-p transistors.
Given a transistor with a β value of 150, design a circuit ensuring a collector current of 2 mA. Identify the base current and explain the biasing requirements.
Think about how changing β impacts collector and base currents.
