2 cards from this section. Quick, good the night before a test.
What is a common emitter amplifier?
Think about how the emitter connects to the circuit.
What does the beta (β) value represent in a transistor?
It's a ratio related to currents through the transistor.
What is the significance of matching transistors in a current mirror?
Think about what happens if transistors behave differently.
Is the voltage gain of the amplifier calculated using Ohm's law?
Remember the equations for gain involve parameters of the active devices.
Given a collector current I_C of 2.2 mA and β of 250, calculate the base current and describe its significance in the operation of the amplifier.
Focus on the relationship between collector and base currents.
Design a current mirror circuit with an output voltage drop of 0.6V. If the supply voltage is 12V, calculate the maximum collector current sustainable in your design.
Apply Ohm's law tailored to the output specifications.
