Schemes of two-half-period rectifiers on op amps with switching inputs in accordance with the polarity of the input voltage are given. The switching of inputs is performed by a control signal taken ...

The use of Operational amplifiers can improve the performance of a wide variety of signal processing circuits. In rectifier circuits, the voltage drop that occurs with an ordinary semiconductor ...

And here it is, modelled using LTSpice. It is the same circuit as the classic simple precision rectifier (set to pass the negative half-sine), but with the non-inverting input of the op-amp connected ...

Diodes has entered the precision low-voltage low-power op-amp fray with a dual-channel 8μV(typ) input offset voltage device consuming 12μA quiescent per amplifier. Diodes has entered the precision low ...

Members can download this article in PDF format. The precision op amp plays a key role in analog and mixed-signal circuits. Applications extend from measuring large currents by amplifying the voltage ...

The op amp dates back to the early 1940s, according to some sources. But it was only in the late 1960s that it adopted its current form factor, with the development of monolithic process technology.

As analog engineers, it’s tempting to fantasize about one day coming close to designing the ideal operational amplifier we encountered in college: infinite bandwidth, zero output resistance, and so on ...

While there is a trend towards integration within the electronics industry, the demand for discrete products appears to remain unaffected. Nowhere is this more apparent than in the analogue world, ...
