what is procedure of ac inverting amplifier using an op amp
Answers
Answer:
In the inverting amplifier circuit the signal to be amplified is applied to the inverting input of the opamp through the input resistance R1. Rf is the feedback resistor. Rf and Rin together determine the gain of the amplifier. Inverting operational amplifier gain can be expressed using the equation Av = – Rf/R1.
Explanation:
Non_inverting Operationeu vu.v' Non_inverting Operational Amplifier The second basic configuration of an operational amplifier circuit is that of a Non-inverting Operational Amplifier design. In this configuration, the input voltage signal, ( VIN ) is applied directly to the non_inverting ( ) input terminal which means that the output gain of the amplifier becomes "Positive" in value in contrast to tHo "invertina Amplifier' " circuit we saw in the me fflVt'ILllig i-\ii'-'''' last tutorial whose output gain is negative in value. The result of this is that the output signal is "in-phase" with the input signal . Feedback control of the non-inverting operational amplifier is achieved by applying a small part of the output voltage signal back to the inverting ( - ) input terminal via a Rf - R2 voltage divider network, again producing negative feedback. This closed-loop configuration produces a non-inverting amplifier circuit with very good stability, a very high input impedance, Rin approaching infinity, as no current flows into the positive input terminal, (ideal conditions) and a low output impedance, Rout as shown below.
