Op-Amp may perform numerous mathematical operations; hence the name operational amplifier. We here consider some of the applications of Op-Amp. Thus, consider the ideal inverting Op-Amp of figure 1 with voltage shunt feedback through Zf. Equation 1 may be used to secure various operations as analog inverter and paraphase amplifier, scale changer, phase shifter, analog adder, current-to-voltage converter etc. …..(1) Analog Inverter Read more […]

## Inverting Operational Amplifier with Voltage Shunt Feedback

The ideal inverting operational amplifier with voltage shunt feedback from output terminal to the inverting input terminal feedback impedance Zf and with non-inverting terminal grounded configuration is shown is figure 1. 25+ verified electronics projects using op-amp 741. This forms the basic inverting op-amp. It is “Inverting” because our signal input comes to the “-” input, and there has the opposite sign to the output. The feedback Read more […]

## Op-amp | Block Diagram | Characteristics of Ideal and Practical Op-amp

What is an OP-AMP? An operation amplifier (Op Amp) is basically a multistage, high gain (Av>105) direct coupled amplifier with two differential inputs and a single ended output and which uses feedback to control its overall response characteristics. It may be used to perform numerous linear operations and some nonlinear operations. An important feature of operational amplifier is that by simply changing the feedback impedance, its operation Read more […]
