An inverting amplifier (also known as an inverting operational amplifier or an inverting op-amp) is a type of operational amplifier circuit which produces an output which is out of phase with respect to its input by 180 o. In an inverting amplifier circuit, if both the resistors R1 and Rf are of equal magnitude Rf = R1, then the gain of the inverting amplifier will be -1, producing an output that is a complement of the applied input, Vout = – Vin. Inverting The amplifier which has 180 degrees out of phase output with respect to input is known as an inverted amplifier, whereas the amplifier which has the o/p in phase with respect to i/p is known as a non-inverting amplifier. The input- output relationship for this circuit is given by (9.2) The electronic circuits which perform the mathematical operations such as logarithm and anti-logarithm (exponential) with an amplification are called as Logarithmic amplifier and Anti-Logarithmic amplifier respectively.. The input voltages are applied to the inverting terminal of the op-amp. Inverting amplifier simulation PSPICE. Hence, V 1 = 0, also. In an inverting amplifier circuit, the operational amplifier inverting input receives feedback from the output of the amplifier. Assuming the op-amp is ideal and applying the concept of virtual short at the input terminals of op-amp, the voltage at the inverting terminal is equal to non-inverting terminal. 3. In addition to this simple calculation, the operational amplifier’s performance must also be considered when configuring a circuit.

This means that if the input pulse is positive, then the output pulse will be negative and vice versa. The multiplying constant in the inverting amplifier is R/RI (which may be less than I), and it is I + RlRI (which is always greater than I) in the noninverting amplifier. The sum of the input signal is amplified by a certain factor and made available at the output .Any number of input signal can be summed using an opamp. Because V+ is connected to ground, the input impedance is just Rin. •= Open loop applications and Comparators – Applications showing an operational amplifier used open loop, as a comparator have been deleted.
