2 cards from this section. Quick, good the night before a test.
Define input capacitance.
Think about what all components could contribute to this capacitance.
What is cutoff frequency?
How does gain relate to this frequency?
What does input capacitance determine in an amplifier?
Think about how capacitance impacts signal behavior.
True or False: Lowering the input capacitance increases the cutoff frequency.
Related to how frequency and capacitance interact.
Given a circuit with a load capacitance of 150 pF, an output resistance of 30 kΩ, calculate the new cutoff frequency of the circuit.
Use the formula for cutoff frequency and plug in the given values.
An amplifier exhibits a voltage gain of 2500 and has an input capacitance of 12 nF. Calculate the effective input capacitance when this gain is applied and find the impact on frequency response.
Use the capacitance formula that includes voltage gain.
