[sdiy] linearize OTA for VCF?

clipping... (with diode bias)

or higher noise and soft clipping.... (without)

I don't know which I'd choose.

Hi Harry:

The way I got around this in my VCA design, which uses the CA3280 with
diode bias activated, is I set the gain levels so that the OTA clipping
point coincides with the output buffer reaching the power supply rail. 
You're going to clip there anyway.
