I think Juergen referred to the 4023 filter. The integrators are
LM301 with a FET buffer in front. The gate (which is at a constant
potential) of the FET is decoupled to ground by means of a 1 nF
cap for RF stability, I gather -- the LM301 obviously isn't terribly
fast.

I think the 4023 is still downloadable in PS format from my "website".
