Inverting Amplifier Question & Answers October 25, 2022 By WatElectronics This article lists 40 Inverting Amplifier MCQs for engineering students. All the Inverting Amplifier Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of Inverting Amplifier. Operational Amplifiers are simply called Op-amps. These are configured as inverting and non-inverting op-amps. In this configuration, the output can be fed-back to the input known as feedback. This concept is applied in various circuits such as filters, oscillators rectifiers, and so on. Two terminals are present in the op-amp positive and the negative one. But feedback applied can be either negative or positive. Output connected to terminal i.e., positive then feedback referred to as positive otherwise negative. A circuit of op-amp producing voltage at the output that changes in the opposite way of applied voltage at the input is referred to as Inverting amplifier. Output produced in such amplifiers is not in phase (i.e., 180 degrees) with the applied input. Feedback in the op-amp is applied through a resistor (Feedback resistor) placed externally. Based on applications to allow control over gain feedback connections is applied in the circuit. Generally, op-amps of inverting type use negatively connected feedback. 1).
