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 ...

Current-mode full-wave rectifiers and precision rectification techniques represent vital advancements in signal processing, enabling the conversion of alternating current (AC) signals into a stable ...

A classic analog application is the precision active full-wave rectifier. Many different implementations exist of this theme, each with its own supposed advantages. However, one circuit element needed ...

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 ...
