if the input is 10V the output is 10V.p.p.
At 6V the output is 8V.p.p
At 4V the output is 5V.p.p. (in the Falstad Simulator, to get an idea on what resistors i have to have at hand, i did build the Circuit as well in LTSPICE).
At 2V = close to 1.6V.p.p.
the VCA starts moving at a control voltage of 1.5V.
That's makes it logarithmic or exponential?
Using the beta calculator of Paul for MOSFETS.

don't know what to fill in, what is RDS(on).RDS(on) (Ω) (use typical value):
VGS where measured (V):
Threshold (V) (use typical value):
default = 20m.
the gates are at 2.5V, halfway using voltage dividers.
What number am i looking for the ALD1105?
