Term: Operating Point
Definition: The DC conditions of the amplifier where the transistor operates in its active region.
Term: Voltage Gain
Definition: The ratio of the output voltage to the input voltage in an amplifier, indicating the amplification capability.
Term: Input Resistance
Definition: The resistance seen by the input signal at the amplifier, influencing how the amplifier interacts with preceding stages.
Term: Output Resistance
Definition: The resistance seen by the output signal of the amplifier, affecting the load it can drive.
Term: Upper Cutoff Frequency
Definition: The frequency beyond which the amplifier's output power falls significantly, marking the limits of the amplifier's effective bandwidth.
