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 ...

A classic analog application is the full-wave precision rectifier (absolute value) function. Many variations exist on this theme, each with its own supposed (often rather minor and sometimes downright ...

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 ...

The circuit in Fig 1b obviates the precision resistors by simply returning the diodes to the input. For a positive signal current, D 1 is on, and the current flows into the load resistor to develop an ...
