Dear Mr Chun,
Amplifier suitable for a low noise receiver applications are OPA820, OPA846, OPA847 for single-ended application, OPA2822, OPA2846 and OPA847 for fully differential applications.
Could you provide more details on your specification…
Hello Ratul,
Thank you for reaching out. We have done similar setup in the lab without a photodiode or AC input current source. The method we use is highlighted below:
This is from a PowerPoint with more details attached below. Make sure that C1…
Hello Deepthi,
I apologize for delay in response. For the best method to test out TIA based device without a photodiode, I would suggest using a voltage source and add a couple passives at the input to the inverting pin of the amplifier with estimated…
The GBP definition, and what you need for TIA design, is the single pole projection to 0dB. Get that by going to the Aol=40dB point and multiplying that frequency by 100X, 1.59GHz here,
This recent article tries to explain this confusion, and also…
Part Number: OPA846 I need to edit this curve, any idea what software created this and perhaps that source file?

Well the transimpedance design has a peaked noise gain shape due to the detector source C, here is a full design flow discussion including noise

I am working from this background information for transimpedance, from which I developed all those datasheet examples for the OP847, OP846, etc. etc. etc.

Part Number: OPA828 Other Parts Discussed in Thread: OPA3S328 So I had gotten involved in what is out there in compensating a transimpedance design, There is a newer one I will mention at the end that seems very accurate, wondering what equation sits…
