2 cards from this section. Quick, good the night before a test.
What is voltage gain?
Think about how much the input signal is magnified.
Define input impedance.
It relates to how the circuit interacts with previous stages.
What is the importance of voltage swing in a common base amplifier?
Consider the output limits set by the circuit design.
True or False: The input impedance of a common base amplifier is generally high.
Think about how input and output impedances relate.
Design a common base amplifier circuit that meets the following specifications: gain of 10, output swing of ±5V, and input impedance of 250Ω. What resistor values would you choose and why?
Consider the relationships between current, voltage, and resistance.
Evaluate the performance implications of a common base amplifier with an input impedance of 50Ω when driven by a 50Ω source impedance.
Think about how matching affects efficiency in electronic circuits.
