OTA as integrator

What are you trying to integrate?
Why do you need to use an OTA?
How will you trigger a reset?

 

The traditional solution would be a Miller Integrator.
See; http://en.wikipedia.org/wiki/Operational_amplifier_applications#Inverting_integrator

 

I'm not sure you can buy OTAs off-the-shelf... I think they are only useful as internal components in an IC. The problem with an OTA is while you can implement simpler integrators with them in theory, they can't drive resistive loads and are therefore less interesting in practice.

 

Yes. That's way people usually use op amps for this type of thing. See Baluncore's post. You want to use a Miller Integrator.

 

Look at
LM13600, LM13700, CA3080, CA3280, LM3080, CA3094, LT3469,
OPA460, OPA461, OPA660, OPA661, OPA860, OPA861, OPA2662
NE5517, MAX435, MAX436, NT996,

 

Well I certainly stand corrected!
