Gate circuit 4066 pop-noise reduction

[knutolai]

So as mentioned in a earlier thread I'm working on a gate-delay. Currently I'm experimenting with using a 4066 gate as, well, the gate. It's working relatively well apart from the slightly annoying transition "pop". So I thought I'd ask for some suggestions. Below is the current very basic circuit:


I've tried operating the switch close to Vref, as described in this article http://www.geofex.com/article_folders/cd4053/cd4053.htm (thx R.G.), but doing that actually make the  transition even noisier. Are there any cheap tricks to try that doesn't involve swapping to a different IC?

I  set the dc level at the switch to 1/2 the supply. The ground referenced dc level you show implies you are using a bipolar supply - is that right?

I posted my experiences resolving this a while back

No I'm using a unipolar supply. You could look at it as a bipolar supply but then the resistors would have been connected to negative. I'll have a look at your fix. thanks!
