auto zeroing to reduce flicker noise
I have designed a fully differential op amp in gain-boosting topology with 0.18µm technology, and i used ELDO simulator. I got input referred noise of 60nV/√Hz at 1KHz frequency, and 3nV/√Hz at higher frequencies.
So can any one suggest how to minimize the flicker noise present at low frequencies.
My specifications are DC gain: 115dB
UGB:1GHz
PD:4.5mW
