3 cards from this section. Quick, good the night before a test.
What parameters must be known to design a common emitter amplifier?
Think about the basic requirements of the amplifier.
How is quiescent current related to power dissipation?
Consider the formula for power in electrical circuits.
What is the formula for voltage gain in common emitter amplifiers?
Recall how gain is derived in operational amplifiers.
True or False: The output swing is determined solely by the collector current.
Consider factors beyond just current when analyzing output swings.
Calculate the necessary parameters for a self-bias common emitter amplifier including quiescent current, collector resistance, and bias resistors when supplied with 10V and a desired gain of 50.
Use the formulas discussed in previous examples.
If a common emitter amplifier designed for a power dissipation of 10mW at a supply voltage of 12V has a quiescent current of 1mA, calculate the collector resistance.
Remember to correctly relate power equations in terms of voltage and current.
