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 ...

Abstract: The paper presents precision full-wave rectifier with two current conveyors, without any passive components and two diodes. The theory of the rectifier operation is described and analyzed.

Abstract: This paper presents a precision full-wave rectifier, which is highly suitable for CMOS technology implementation. The system comprises a voltage-to-current converter, precision full-wave ...

EE JULY/AUGUST 1987 This precision rectifier oper- ates from an asymmetrical supply, handles input signals up to 3Vpp and has a frequency range that extends from DC to about 2 kHz. Its amplification ...

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 ...

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 ...
