2 cards from this section. Quick, good the night before a test.
What is the formula for calculating input capacitance?
Consider the different capacitance components and how they combine.
Define transconductance.
What is it indicative of in a circuit?
What does input capacitance affect in an amplifier?
Consider both aspects of performance metrics.
True or False: The gain of a cascode amplifier is generally lower than that of a common emitter amplifier.
Reflect on the advantages of cascode designs.
Design a cascode amplifier with a bias current of 5 mA. Calculate the input capacitance given specific transistor parameters.
Ensure you take into account the voltage gain ratios accurately.
Evaluate the implications of increasing transistor β on input capacitance and system bandwidth.
Focus on how gain interactions and capacitance values respond to the changes in bias settings.
