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 ...

Conventional rectifiers employing diodes can’t be used with low-amplitude signals. This Idea for Design describes a circuit using Analog Devices' AD844 op amps to create a mixed-mode precision ...

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 ...

What applications require precision op amps? Precision amplifiers originally evolved to fill the needs of the test and measurement community. This arena demanded test system elements with much more ...
