Schemes of two-half-period rectifiers on op amps with switching inputs in accordance with the polarity of the input voltage are given. The switching of inputs is performed by a control signal taken ...

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 ...

NAMM 2025 might have us all focused on what’s new but maybe the biggest story to come this month in guitar amplification will have have us in a nostalgic mode, taking us all the way back to 1992 as ...

Engineers often encounter difficulty when attempting to accurately rectify low-amplitude AC signals using standard diode-based circuits. The primary issue arises from the diode’s forward voltage drop, ...
