You can combine a carefully chosen op amp, a low-threshold P-channel MOSFET, and two feedback resistors to make a rectifier circuit with less forward drop than a diode (Figure 1). The rectified output ...

Power supplies that use diodes to rectify an ac voltage to obtain a dc voltage must deal with inherent inefficiencies. A standard diode or ultra-fast diode can have a 1-V forward voltage or higher at ...

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 diode is a device that allows current to flow in one direction but not in the other. This ability makes diodes useful in many applications, including converting AC to DC, regulating voltages, and ...

In the realm of modern electronics, semiconductor diodes have emerged as fundamental components with diverse applications. One of their pivotal roles lies in the fields of rectification and voltage ...
