3 cards from this section. Quick, good the night before a test.
What is the voltage gain of the discussed cascode amplifier?
Recall the earlier calculations in the session.
Define input capacitance in the context of an amplifier.
Think about what capacitance affects in a circuit.
What does the input capacitance depend on in a cascode amplifier?
Consider how modifications in gain and resistance interplay.
True or False: Higher gain in a cascode amplifier always results in a higher input capacitance.
Remember the relationship defined in the section.
Given a cascode amplifier with C_gs1 = 12 pF and C_gd1 = 7 pF and a voltage gain of -40, calculate the new input capacitance.
Substitue the values carefully into the formula.
Investigate how changing small-signal parameters affects both gain and capacitance in the circuit if you switch from using MOSFETs to BJTs.
Research the inherent differences between BJTs and MOSFETs to support your analysis.
