Term: Current Mirror
Definition: A current mirror is a circuit configuration that copies a current through one active device to another, maintaining constant current regardless of load conditions.
Term: Voltage Gain
Definition: Voltage gain is defined as the ratio of output voltage to input voltage in an amplifier, indicative of the amplifier's ability to increase voltage.
Term: Early Voltage
Definition: Early voltage is a parameter used to represent the output resistance of a BJT in active mode, affecting the current gain and output characteristics of amplifiers.
