  • RE: OPA855: Question About Using OPA855 for Differential TIA Design

    Hello, We apologize for the delay. I was able to review your question, and in a true transimpedance application, the gain will be fixed by Rf. OPA855 can work as a differential amplifier, but not in the method you have shown for a transimpedance application…

  • RE: OPA855: I have a dc bias problem when use opa855 as C-TIA

    Resolved
    I am planning to use an AGC structure after the TIA. But, The noise of the TIA limits the system's dynamic range due to its impact on the signal-to-noise ratio (SNR). So, I am conducting research on low-noise and low-gain TIAs implemented in CMOS…

  • OPA855: OPA855 as a transimpedance amplifier

    Part Number: OPA855 Tool/software: I would like to use your OPA855 as a transimpedance amplifier for a 2.5GHz photo diode detector. I need 2.5GHz bandwidth. Using your “Application Report SBOA122–November 2009” I should be able to get there.…

  • OPA855: Faulty Simulation how do I get the netlist from TINA TI?

    Part Number: OPA855 Other Parts Discussed in Thread: TINA-TI Tool/software: I had a faulty simulation using a design featuring the OPA855, I took the reference design simulation which was a fixed gain amplifier and changed it to a transimpedance amplifier…
