What is the formula for voltage gain?
Think about how output and input voltage relate.
Define transconductance.
It involves current and voltage changes.
What is the formula for voltage gain?
Consider how you measure output in context of input.
True or False: Cascading stages decreases overall bandwidth.
Think about additive benefits of multiple stages.
Design an amplifier with a desired voltage gain of 20 and calculate the required g_m and R_D if you have a 4kΩ resistor available.
Think of rearranging the gain formula to determine your variables.
Given a common source amplifier with a bandwidth of 600 kHz, if you cascade it with a common drain amplifier, achieving a total bandwidth of 3 MHz, what can you conclude about the design efficiency?
Reflect on how adding stages affects performance metrics.
