For the gain control: you can make a multiplier function that has a gain of -40db at 0.4V, 0db at 0.7v , and +40db at 1V.
It will tale a little work to limit the gain to +40db.
"muting" the gain below 0.4V will take some work.
The output is just a power amp with a gain of 1.
I don't see a spice model. If you build a function it will only be partly accurate. You should limit the bandwidth and slew rate to get closer.
I am in difficulties in defining the multiplier function...
Could you help me please?
hi,I have not yet created the file because I do not know how define the function....i try to think something...
I know that
Vout=Vin*G
where G=F(Vdc)... G it is not simply log(Vdc) right?
