Three opamp instrumentation amplifier - how to compensate?

[thatsthebadger]

I'm designing a low noise instrumentation amplifier with the usual three opamp circuit. The frequency response is a bit high and a bit peaky at the top end. However, it only needs to be up to around a few kHz so I would like to kill off the response in a nice controlled way by adding some caps in the feedback paths or something... any suggestions?

I've never heard about combining a instrumentation amplifier with filter components.

The closest I get an answer by search on the web was **broken link removed**, and a payment site that take charge to allow you to download a chapter (may be scam).

Most probably, the peaking at the end of the frequency band results from both input amplifiers (phase margin smaller than 60 deg). However, since your operating frequency is only a few kHz - why do you care about this?
