Precision Rectifier

A sturdy rectifier for very small signals. It uses two operational amplifiers and two diodes. Even though the diodes only conduct when their voltage reaches 0.7V, with a precision rectifier they work for smaller voltages too.

I did not "invent" this circuit. It's from the book "Elektrische Messtechnik" (Lerch, Kaltenbacher).
