Hi,

I read the paper and I realized something. Appearently, this method reduce the actual "signal" gain to unity, however, noise gain stays at the minimum gain within some certain bandwidth.

That means G=10 applied to noise, but the signal goes through without gain. I am worried that such increase in noise level may be very bad ...

Help me, oh so great ones of the hall of wise!

Tomo

Tomo,

The OPA power op-amps from Burr-Brown are unity-gain stable.
No fuss.
You can try the OPA548.
