Only Duty-Cycle Correction

00:47:49

Works over a wide frequency range. For example, 100kHz to 2MHz. You have to wait a long time or play in EC with gatedelay to be able to simulate faster.

You just need an XOR and a delay filter. You have here a low pass filter of second order which takes away all harmonics and left over a DC operating voltage level, but with a small ripple, which is importante to work as frequency doubler. So you even close to not work as doubler you are lucky the gain of a logic gate is high enough to be amplified and the XOR can do its doubling job as you wish. So take away your OpAmp and just use a single first order low pass and it will work much better as frequency doubler.

and your duty cycle corretion is unclear how this should work, check the OpAmp removed version here http://everycircuit.com/circuit/4632987518631936

Now it is only a Duty-Cycle Optimizer...
