Term: Common Collector Amplifier
Definition: A type of amplifier configuration where the collector terminal is common to both input and output, providing high input impedance and low output impedance.
Term: Common Drain Amplifier
Definition: An amplifier configuration similar to the common collector, but utilized primarily in MOSFET circuits where the drain is common to both input and output.
Term: Voltage Gain
Definition: The ratio of the output voltage to the input voltage, indicating how much an amplifier increases the power of a signal.
Term: Input Capacitance
Definition: The capacitance presented by the input terminals of the amplifier, which can affect frequency response and stability.
Term: Output Resistance
Definition: The equivalent resistance seen from the output terminals of the amplifier, which affects the loading conditions and the signal delivered to the next stage.
