Re: opamp
make your input differential pair with big w/l, pay attention to the match of the current mirror, and you also need to reduce the system offset.
Re: Help!!!What is "pwell soft connected", a DRC e
soft connection means two well or two diff region connectted only through well or diff, there is no metal connection between them.
Thank you,willyboy19
What you mean is that when we design the op-amp used in the integrator,we need not to have a phasemargin larger than 45(or 60),why can we do it in this manner? would the op-amp oscillate in lower frequency than the close loop bandwidth? perhaps the feedback capacitor of the...
The stability of integrator/filter is decided by which factor? what is the infect of the feedback capacitor? Could we think that if the op amp is frequency stable and its GBW is large enough, then the integrator/filter is stable?
Hello,I am designing a 2-order LPF,but I don't know how to do the simulation of AC characteristics for closed loop LPF and open loop LPF,can somebody help me?
Thanks a lot!
op amp single-end differential
I am designing a op amp,the first stage is differential output and the second stage is single-end output,need I add a CMFB circuits to the op amp for the first stage?
