the Fig.10 from http://sound.whsites.net/appnotes/an001.htm yielded the best result in simulation - so far - of what i have tested (*)
/// -- i needed a fast ideal diode for a simple analog voltage multiplier or VGA circuit -- such that responds correct asap. after the zero crossing
!!! but it may be due false/ideal/simplified behavior of the Ge 1N34A ((the Russian analogs i have are capable of ?something? 40MHz)) -- using the Si 1N4148 makes the picture a lot more poor !!!

_/¯\_/¯_/¯ the "drift-delay" stands for the time that it takes for the output to catch up with the input after each zero crossing (*)
