Hi,
I have a photodiode equivalent like this:
Can I transform this equivalent in a series between a voltage source (Vg) and a resistance (Rg).
Because this photodiode is the input of the negative pin of an opamp that work like an integrator to amplify photodiode's signal and I need to calculate...
Ok thanks!
So M5-M6 is a source follower to optimize the transfer of energy to load, and M7-M8 are the biasing transistor of the source follower stage.
It is correct?
yes it is only a sketch that I use to calculate the output range, but I know that a Vcm is needed!
Thanks for your patience...
Thank you for your fast reply.
So it' equal to this other circuit: (the only difference is that M5,M6 are pMos instead of nMos, what is change??)
So in this case the total differential gain is:
ATOT = 2 x gm1 x (ro1||ro3) x gm5 (ro5||ro7)
it's correct?
Thanks in advance
Hi,
I have this type of circuit to analyze:
1) What is the kind of topology of this circuit? because it is similar to a OTA fully diff but there are 2 differential pairs(M7-M8 and M1-M2), one with Vo and another with differential and common input
2) What is the differential gain Ad?
if you...
