Hi,
I'm a beginner to analog design. I'm working on a project with a spec as follows:
*****
supply 1.8 v
input range p-p 0.9+-250mv pp500mv
output range p-p diff 1v
unity gain bandwidth 1G
phase margin >60
power consumption<20mw
load 1.5pico
*****
My first question is, here, input differential voltage is p-p 500mv and output range is 1v. Does that mean, the Av = 2?
2nd, I want to use telescopic cascode. Do I need to worry about the input signal range? In Razavi's example, he doesn't take the input range into account. But why?
3rd, here I have to get GBW = 1G. How can I start to meet this requirement?
Thanks for any advice in advance.
