Which amplifier uses the base as the reference terminal for the input and output signal?
The amplifier that uses the base as the reference terminal for the input and output signal is the common-base amplifier. In this configuration, the input signal is applied to the emitter, while the output is taken from the collector. The common-base amplifier is known for its high frequency response and low input impedance, making it suitable for specific applications such as radio frequency amplification.

Why drain is called common in common drain amplifier?
The term "common" in a common drain amplifier refers to the configuration where the drain terminal of the transistor (typically a MOSFET) is connected to a common reference point, usually ground. In this configuration, the input signal is applied to the gate, and the output is taken from the source, making the drain the terminal that is common to both the input and output. This setup allows for a high input impedance and low output impedance, making it useful for various amplification applications.
What does an amplifier do to a small input signal?

What is the output signal of a common base amplifier?
3Db
What must be supplied to an amplifier in order for it to be able make the output signal bigger?
To amplify a signal, an amplifier must be supplied with a power source, which provides the necessary energy to increase the amplitude of the input signal. Additionally, the amplifier needs a suitable input signal that it can process. The amplifier's design and gain settings determine how much the output signal will be increased relative to the input.
What is a cs amplifier?
A common-source (CS) amplifier is a type of field-effect transistor (FET) amplifier configuration that provides voltage amplification. In this setup, the input signal is applied to the gate terminal of the FET, while the output is taken from the drain terminal. It is characterized by its high input impedance and moderate output impedance, making it suitable for interfacing with high-impedance sources. The CS amplifier is widely used in analog circuits due to its simplicity and effectiveness in amplifying signals.
What is Op-Amp non inverting amplifier?
When the feedback of the output terminal of an Op-Amp is given to the non-inverting terminal [pin 3 for IC-741] of that Op-Amp , then , that circuit is called non-inverting amplifier using Op-Amp. This circuit is called non-inverting because the output signal of this circuit is in phase with the input signal.

Are amplifiers input or output devices?
An amplifier is both an input and output device. An amplifier, as its name suggests, amplifies a signal, meaning that it makes it stronger. An amplifier takes something as input, like maybe a sound signal, and its output is a more powerful (or louder) version of the same signal.
What must be supplied to an amplifier in order for it to be able make the output signal bigger?

What is the ratio of the output signal to the input signal of an amplifier that is usually measured in decibels?
Answer is GAIN

Why is the output signal affected if the impedance of the amplifier and the load do not match?
A: The signal output will not change it is just that the efficiency of power transfer is effected to less
What is the use of operational amplifiers in circuits?
An operational amplifier is typically used where it is desirable to control a voltage over a wide range of levels; i.e., in analog mode as opposed to the on-off limits of a digital signal. An operational amplifier in simplest form will have a non-inverting and an inverting input terminal and an output terminal, each of which are analog in function. The output terminal will tie into external circuit components that eventually connect back to the inverting terminal. The key to its performance is that when a change is made to the voltage on the non-inverting input terminal, the output of the amplifier will change in voltage level, whether increasing or decreasing, to the level that causes the voltage appearing at the inverting terminal to equal that of the non-inverting terminal. In that way the output voltage is a predictible value that is useful for automatically controlling a flow valve or other device. Of course, it can also be used to just to act as a signal conditioner for sensors, audio devices and countless other applications.
What is the ideal dc value of output signal when there is no input signal in class b amplifier?
A: If the input is zero the desire output is zero no matter what class it is.
