Inverting Operational Amplifier
What is the gain of Inverting Operational Amplifier?
Inverting Operational Amplifier are used for amplifying an input signal. The gain of an amplifier is defined as factor by which the input signal is amplified to generate the output signal. Gain is negative for Inverting Operational Amplifier.
What is the use of two resistors used in Inverting Operational Amplifier?
The inverting op-amp has two resistors. The feedback resistor is connected between the output and the inverting input of the op-amp and input resistor is connected between the inverting input of the op-amp and the input signal source. Together Rf/Rin is used to determine gain.
What is the concept of virtual earth in Inverting Operational Amplifier?
This concept is applicable to an ideal op-amp as a result of negative feedback applied. It states that for an ideal op-amp with negative feedback, the voltage difference between the inverting and non-inverting input terminals is virtually zero.
Inverting Operational Amplifier
Operational amplifiers are an important category of instruments used in electronics engineering. Often they are used for the task of amplifying the output. In this category of instruments, there is a subcategory known as Inverting Operational Amplifiers. They are typically used when we need an opposite phase for the input waveform.
