Hello,
can you possibly suggest a suitable operational amplifier for the customer's application as per the below description?
-----
We are looking for amplifiers on DIE-level which we can integrate into our terahertz detectors.
These detectors are down-converting the incoming terahertz signal, so that the detector current is either in the kHz to MHz range, or extends into the lower GHz range, depending on the application.
The noise current of our detectors is between 20 pA and 100 pA, which is why we need very low-noise amplifiers.
The signal amplitude reaches up to a few µA. Signals with around 10 nA should be able to be detected by the amplifier in any case.
The output amplitude should then be large enough for the signals to be digitized by an ADC.
A cascading of several amplifiers is of course conceivable.
The requirements regarding the bandwidth are concrete:
For spectroscopy and measurement technology, the amplifier should have a bandwidth of > 500kHz.
Bandwidths> 5 GHz are required for communications applications.
I would be very grateful for your recommendation.

Can you possibly suggest possible op amps that could be suitable for this use?
Would you need any additional details before you can suggest a specific part?
Thank you very much.
Best regards
