Key Concepts
- -- Common Collector Amplifier
- A configuration that provides high input impedance and low output impedance, often used for impedance matching.
- -- Voltage Gain
- The ratio of output voltage to input voltage in an amplifier, indicating how much the amplifier increases the signal amplitude.
- -- Upper Cutoff Frequency
- The frequency above which the gain of the amplifier begins to decrease, indicating the bandwidth limit of the amplifier.
