This chapter delves into the linear models of amplifiers, particularly focusing on various types such as voltage amplifiers, current amplifiers, transconductance amplifiers, and transimpedance amplifiers. Each type is modeled to simplify the circuit while capturing essential characteristics like input-output relationships, voltage gain, and loading effects. The importance of understanding these models is emphasized for handling complex circuits and enhancing practical comprehension within the field of electronics.
Different types of amplifiers exist based on input and output signal types.
The relationship between input and output can be represented using equivalent linear circuits.
Loading effects at both input and output ports are important considerations in amplifier design.
An amplifier that increases the voltage of a signal, maintaining a linear output relative to the input.
An amplifier that boosts the current of a signal, with the output current depending on the input current.
An amplifier that converts input voltage to output current, with a transfer function based on input voltage.
An amplifier that converts input current to output voltage, emphasizing the relationship between current input and voltage output.
The impact on an output current/voltage due to the connection of a load resistance, which can alter the expected output signal.
