about push-pull cmos ota
Does anyone know a complete reference on the push-pull cmos ota (picture is in:
**broken link removed** page 2) ?
What are the advantages of using the push-pull single ended output configuration like in the picture above? besides the controllability of the zero?
Thanks
would like to ask if anyone has links/references to basic of ota, especially current-mirror ota used in the bioamplifier (like the one used by harrison in his paper for neural amplifier)
one of the thing i want to know is the gain bandwidth equation, which i was told as gm/CL. but when it is...
Re: about micro power design
Hi ambreesh,
we actually don't really use gm/Id method in calculating the aspect ratio, we just use it for estimation on how the parameters can be increased/decreased to get the spec wanted.
we use HSPICE. it is very difficult to match the calculation result to...
about micro power design
i would like to ask if anybody know the suitable bias circuit (with startup) for micropower design. the standard topology (for strong inversiong) used now can give current about 45 nAmp, but there's a problem with the speed and stability. the SR+ and SR- are very far...
psrr simulation
i've been doing the PSRR simulation with definition: PSRR- = Av(vss=0)/Ass(vin=0)
it means that when i measure Av, i put ac signal at i/p +ve of unity gain op amp, and when i measure Ass, i put ac signal at the vss. is that the correct way of doing it?
what is the value of the...
measure psrr op amp
ow.. yap.. thanks jordan76
btw, may i ask some other questions in this topic?

psrr opamp
the positive input should be tied to ground? but then some transistors will be cutoff, since i use power supply from 0 to 3V. Up till now i always put common mode voltage in the +ve i/p. can i?
