Schemes of two-half-period rectifiers on op amps with switching inputs in accordance with the polarity of the input ... When a negative half-wave of the corresponding amplitude arrives at the input of ...

So far, I had a promising idea for a half-wave rectifier that didn’t need any diodes or analog switches. Super. But I wanted full-wave rectification. Nothing for it but to add a second op amp, IC1b.

High-Speed Full-Wave Rectifier Requires No Diodes, Few Parts June 7, 2007 Systems requiring power conversion and level detection employ full-wave rectification, traditionally provided by a diode ...

Here, we report on a rectifier based on a pentacene diode that can rectify an incoming a.c. signal at 50 MHz. At 14 MHz, a rectified voltage of 11 V for an a.c. voltage with a peak-to-peak ...
