Re: High speed amplifier
Thank you for your help.
I tried many amplifier architectures.
The first one I used was the folded cascode with Class AB floating current source as an output stage. The major problem with that structure was it was too much power consuming. Indeed, I had to use near 3.5...
Re: High speed amplifier
Thanks for your help. One of my other concerns is to maintain a power consumption lower than 10 mW.
A little update on my progression: my amplifier can drive 60 pF load with 2.8 mA current consumption near 10/12 Mhz. I still have some stability issues to study.
I hope I...
Re: High speed amplifier and analog multiuplexing
Thanks for your answer.
Indeed, I saw it on Razavi's book, that's what motivated my choice.
At this time, I have another problem with this kind of amplifier: I use it for a pixel sensor application, and I need to multiplex many columns on one...
Re: High speed amplifier
Nobody have an idea ?
Little update: I am unable to drive 35 pF with a single telescopic cascode stage.
So I am currently designing a class AB output stage.
I am not sure that gain boosting will help improving the speed (slew rate, settling time) of my amplifier, what...
what do you meant by speed of amplifier
Hello,
Fisrt of all, I will present myself: I come from technology process and I am a beginner with analog design (I am on training now).
I need to design a unity gain amplifier working at 40 Mhz (0.35 um technology with 3.3V). The main limitation is...
