Everyone loves a full-wave bridge rectifier, but there’s no denying that they aren’t 100% efficient due to the diode voltage drop. Which isn’t to say that with some effort we cannot create an ideal ...

A classic analog application is the precision active full-wave rectifier. Many different implementations exist of this theme, each with its own supposed advantages. However, one circuit element needed ...

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 ...

Why harvesting low-level RF is difficult. How a new spin-rectifier implementation addresses a major limitation. The results achieved with the new component. Energy harvesting has lots of positive ...

A plastic 4-pin base with tipless domed envelope. Stamped on envelope: "83". Donor’s card reads: “Full-wave mercury vapor rectifier made by the Radio Corporation of America about 1935 or before.
