Loading effects at both input and output ports are important considerations in amplifier design.
Voltage Amplifier
An amplifier that increases the voltage of a signal, maintaining a linear output relative to the input.
Current Amplifier
An amplifier that boosts the current of a signal, with the output current depending on the input current.
Transconductance Amplifier
An amplifier that converts input voltage to output current, with a transfer function based on input voltage.
Transimpedance Amplifier
An amplifier that converts input current to output voltage, emphasizing the relationship between current input and voltage output.
Loading Effect
The impact on an output current/voltage due to the connection of a load resistance, which can alter the expected output signal.
