Hi guys,

I have a question here. I'm designing a differential input amplifier with a integrated CMFB circuit. I'm operating the amplifier in 1GHz frequency. My question is should I consider about the low frequency noise (1/f flicker) noise in my design, I'm asking this because the amp is designed to work at a data rate of 1Gbps and I consider whatever noise to be integrated is the high frequency noise with dependent with bandwidth but not sure how this low frequency noise become a factor here. Thanks.
