Hi All --

I came across an article by Bob Pease on dielectric absorption, also known 
as soakage in capacitors.  This is an important consideration to anyone 
building long-period analog filters and integrators.  About halfway down 
the article is Figure 6, which is a schematic of a circuit that seems like 
a way to negate most of this effect with large capacitors such as 
electrolytics and mylar.

Note that the article was written almost 20 years ago.
