3 cards from this section. Quick, good the night before a test.
What is the formula for transconductance (g_m)?
Think about how input and output relate in the context of voltage.
Define the term 'cascode amplifier.'
Remember the structure involves stacking two amplifier stages.
What is the primary advantage of a cascode amplifier?
Think about performance characteristics and their relation to signal fidelity.
True or False: The output resistance of a cascode amplifier is typically lower than that of a common emitter amplifier.
Consider the structural differences between the amplifier types.
A cascode amplifier uses two BJTs in series with a collector current of 3 mA and Early voltage of 150 V. Calculate the output resistance.
Apply the Early voltage and Collector current relationship.
Given a cascode amplifier circuit with an input capacitance of 30 pF and transconductance of 500 mS, what is the cutoff frequency?
Consider the impact of capacitance on frequency response in amplifiers.
