I think this is what John wants. B&KTR 961 Reduction of Nonlinear Distortion in Condenser Microphones by Using Negative Load Capacitance .................................................. .................... 19 by Erling Frederiksen It contains a full mathematical derivation of distortion as related to load capacitance, with verification by mechanical measurements.

Johnson's derivation of the noise of an RC network is taught by sophomore year, so what?

There is an equation around somewhere as well. That is what I was first looking for, but the GRAPH that you found, Dimitri SAYS IT ALL! Thanks.

Lavry paper applies only to sigmadelta conversion.

Here is another important graph:

However, if they were dealing with high parasitic capacitance of resistors, they were right. Were they multilayer?
