    Amplifier
In summary, an inverting amplifier is an electronic circuit that produces an output signal that is the inverse of the input signal. It works by using an operational amplifier and two resistors to create a negative feedback loop. The benefits of using an inverting amplifier include high input impedance, low output impedance, stable gain, and ease of design. The gain of an inverting amplifier is determined by the ratio of the two resistors in the feedback loop. Some common applications of inverting amplifiers include audio and signal processing circuits, instrumentation and measurement circuits, and feedback control systems.

Just a simple question about the Op-amp.

For inverting amplifer circuit, if I connect the positive terminal of the power supply to the Vcc, and the nevgative terminal to the Vee. What will happen to out put signal related to the in-put signal?

Thanks.

Without knowing any more than you have told us, who knows...

Positive power always goes to Vcc and negative always goes to Vee. Those remain the same no matter how you configure your op-amp.

The output signal in an inverting amplifier will be an amplified and inverted version of the input signal. This means that if the input signal is positive, the output signal will be negative and vice versa. The amount of amplification is determined by the ratio of the feedback resistor to the input resistor, known as the gain of the amplifier. Inverting amplifiers are commonly used in audio and signal processing applications.
 

What is an inverting amplifier?

An inverting amplifier is a type of electronic circuit that produces an output signal that is the inverse of the input signal. This means that if the input signal increases, the output signal decreases, and vice versa. It is commonly used in audio and signal processing applications.

How does an inverting amplifier work?

An inverting amplifier consists of an operational amplifier (op-amp) and two resistors. The input signal is connected to the inverting input of the op-amp, while the non-inverting input is connected to ground. The output signal is taken from the output of the op-amp. The two resistors form a negative feedback loop, which causes the output to be the inverse of the input.

What are the benefits of using an inverting amplifier?

An inverting amplifier has a high input impedance, meaning it won't draw much current from the input signal source. It also has a low output impedance, making it suitable for driving low impedance loads. Inverting amplifiers also have a stable gain and are easy to design and implement.

What is the gain of an inverting amplifier?

The gain of an inverting amplifier is determined by the ratio of the two resistors used in the negative feedback loop. The gain can be calculated using the formula -Rf/Rin, where Rf is the feedback resistor and Rin is the input resistor. For example, if Rf is 10kΩ and Rin is 1kΩ, the gain would be -10.

What are some applications of inverting amplifiers?

Inverting amplifiers are commonly used in audio and signal processing circuits, such as in audio mixers, equalizers, and filters. They are also used in instrumentation and measurement circuits, such as in strain gauge amplifiers and thermocouple amplifiers. Inverting amplifiers are also used in feedback control systems, such as in motor speed control and temperature control systems.
