The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...

An op-amp operates on analog input. It can be used to amplify or attenuate this input, and to carry out mathematical operations such as addition, subtraction, integration, and differentiation. Because ...

In some applications, a linear amplifier is required which has different gains with regard to the polarity of the input signal. Figure 1 shows an inverting amplifier which is linear within the second ...

Though sometimes taken for granted, designers shouldn’t overlook the intricacies of voltage- and current-feedback op amps—integral players in the analog and mixed-signal worlds. Op amps amplify tiny ...

Op-amp in open-loop configuration has a very few application because of its enormous open-loop gain. Controlled gain can be can be achieved by taking a part of output signal to the input with the help ...
