[sdiy] CD4007 analog switch article?

[Barry Klein]

Hi guys,
Back in probably the late 70's there was an Electronic Design  or EDN design 
note
that described using a 4007 at the input and feedback of an op amp as an 
analog switch.
It had wider signal range, less distortion, and less switching artifacts 
than just using a 4066.
Anyone have a scan of that article?  I probably have it but hidden in a 3 
foot stack of like material.
I tried Goggling but only found someone describing it but not providing the 
article...
