fpm, I think a couple of points aren't clear here. Pls confirm my assumptions:
* UGB here is unity-gain bandwidth of your opamp with the feedback broken (i.e. open loop, but still providing an equivalent loading to your opamp)
* your labels state PGA (programmable gain amp?), but it's probably...
I don't think this forum forbids helping people with exam questions, and plenty of time has passed since the question, so I'm probably Not violating any rules here:
1) frequency modulation signal's spectrum translates to the final signals bandwidth. I don't know why you also have a deviation...
So this makes sense to me like so:
On top of p. 271 at your link, I see the equation you are referring to. Vinpp designates the max input swing you can have, while the source-follower's transfer function is still valid. Source follower's transfer function is Vout~=Vin+Voffset (it's ~= because...
A comment on your sentence re resistor divider:
The input signal amplitude is not just divided between R1 & R3 as in your calculations. It is instead divides btwn R1 & R2//R3 (R2 in parallel w/ R3). This is because both GND and the 2.5V DC reference from opamp are not moving, so from the point...
