2 cards from this section. Quick, good the night before a test.
What is the upper cutoff frequency?
Consider what happens to the gain of the amplifier at this frequency.
Define bandwidth in the context of an amplifier.
Think about how bandwidth relates to cutoff frequencies.
What defines the upper cutoff frequency in amplifiers?
Remember the definition of cutoff in relation to gain.
True or False: Bandwidth is the difference between the upper and lower cutoff frequencies.
Think about how frequencies relate to amplifier functions.
Design a common base amplifier circuit with a specified gain of 150. What parameters must you consider to ensure the bandwidth is sufficient for high-frequency applications?
Think about the relationship between gain, impedance, and frequency response.
Given a common gate amplifier circuit with an input capacitance of 20 pF and a source resistance of 1 kΩ, calculate the lower cutoff frequency if the designed upper cutoff frequency is 10 kHz.
Resistances and capacitances interact; use their formulas wisely.
