The Summing OPAMP Amplifier
https://www.electronics-lab.com/article/the-summing-opamp-amplifier/
Introduction In most of our previous tutorials concerning operational amplifiers, only one input was applied to either the inverting or non-inverting op-amp’s input. This new article will deal with a configuration known as the summing amplifier which gives an output that is proportional to a weighted sum of the multiple inputs present. The inputs can […]
OPAMP Differentiator
https://www.electronics-lab.com/article/the-differentiator-amplifier/
Introduction In our previous article about the Integrator op-amp, we have seen that the implementation of a reactive component significantly changes the electrical behavior of OPAMPs in comparison to fully-based resistive designs. Indeed, the presence of a capacitor in the feedback loop constitutes the main aspect of integrators, which perform electrically the mathematical operation of […]
OPAMP Integrator
https://www.electronics-lab.com/article/op-amp-integrator/
Introduction In most of our previous tutorials related to operational amplifiers, the configurations were based on amplifiers with resistors as part of the feedback loop, voltage dividers, or to interconnect many op-amps. This new tutorial presents a configuration called integrator in which a reactive component (capacitor) is added in the design. In the first section, […]
OPAMP Comparators
https://www.electronics-lab.com/article/opamp-comparators/
Introduction In most of the previous operational amplifier tutorials, the circuits had a feedback loop to the inverting input. This design is the most common because it provides indeed stability and avoids undesirable saturating effects and, it is also common to call it the linear mode. On the other hand, when no feedback is applied […]
Inverting OPAMP
https://www.electronics-lab.com/article/inverting-opamp/
Introduction The previous tutorial about the non-inverting operational amplifier has shown all the details of this op-amp configuration that takes the input signal on the non-inverting pin (+). This could be done by studying the ideal and real models and demonstrating all the important formulas. In this new tutorial, the same approach will be proposed […]
Non-inverting OPAMP
https://www.electronics-lab.com/article/non-inverting-opamp/
Introduction The voltage signal applied to an op-amp can either be supplied to its non-inverting input (+) or the inverting input (-). These different configurations are simply known as a non-inverting op-amp, and inverting op-amp. In this tutorial, we focus on the non-inverting configuration and present its details. An overview of the non-inverting op-amp will […]
