another (virtual) absolute (ideal diode) circuit

the Fig.10 from 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 !!!
