3 cards from this section. Quick, good the night before a test.
What is the primary function of a cascode amplifier?
Think about what happens when you stack amplifiers.
Define small-signal parameters in the context of amplifiers.
These parameters help simplify complex circuits.
What is the primary advantage of using a cascode amplifier compared to a common emitter amplifier?
Think about how cascading amplifiers affects their operating characteristics.
True or False: The early voltage is directly related to output resistance in a BJT.
Consider the role of early voltage in the transistor characteristics.
If the early voltage is increased, what is the expected impact on the output resistance and operating speed of the cascode amplifier?
Consider how resistance and speed correlate in amplifier design.
Calculate the total input capacitance of a BJT cascode amplifier with C_pi = 10 pF and C_mu = 5 pF, considering the voltage gain of the amplifier is 100.
Apply the formula for input capacitance with gain.
