>> I started with this: http://www.sdiy.org/juz/I_01a.png - pretty much every combo I tried, the output waveform of the active integrator wanted to head south.  

> 2. A high value bleed resistor across the cap should help.  But your input resistor is already way high.  So you'll want to scale that down, and the cap up.


Thanks Don - that's a big improvement.

Cheers.
