Part Number: OPA855 Tool/software: Hello, everyone.
I am currently going to build a TIA circuit using OPA855, I want to make the TIA bandwidth up to 1.7GHz, and I am designing it based on the values from the TIA calculator. But the bandwidth of the simulation…
Part Number: OPA855 Tool/software: Hello, I made a transimpedance amplifier with opa855.
I use the fast laser pulse(edge time is 1.5ns) and avalanche photodiode(rise time 0.6ns).
So, I have a problem associated with stability.
opa855 is stable with almost…

Hello team, I am a beginner in TIA. I am now trying to build a TIA circuit using OPA855 to achieve bandwidth=2Ghz and Gain≈4. I have built and simulated the circuit using Pspice but the simulation results are not correct…
Part Number: OPA855-Q1 Other Parts Discussed in Thread: OPA855 We are developing Lidar by applying OPA855-Q1. OPA855-Q1 product bandwidth is 8GHz. The PD Bandwidth we are applying is 2GHz. We use the product at 100MHz. Is it possible for the product to operate…
Hi,
The reason you are seeing this disturbance is because the simulation is reaching an output limit. Although in a real-world scenario the device will saturate and reach a final level, the model is likely not clamping correctly. Despite the model error…
Part Number: OPA855
Hello,
I am trying to use the PSpice model for OPA855 in Cadence Virtuoso. The testbench I am using is quite simple (depicted below):
During transient simulation, I receive a few dozen of the following error:
After researching …
Part Number: OPA855 Other Parts Discussed in Thread: OPA858 Hi Team, I'm experiencing Bias issues when using Models from the OPA855 Unencrypted PSpice Model Package (Rev. D).
As shown in Fig. 1, it is an inverting amplifier with a gain of -10 V/V…
Hello Nick,
I have a similar problem. Can you please give me some advice?
I use OPA855 as a TIA. The SIPM's output voltage is 32mV, rise time is 1.3ns, capacitance is 555pF.
I calculate the bandwidth is 270MHz by the equation is rise time (tr)=0.35…
Part Number: OPA855 Other Parts Discussed in Thread: OPA858 , I am trying to develop a transimpedance amplifier for SiPM/MPPC silicon photomultipliers. I need wide bandwidth and low gain. I developed a system based on OPA855. In practice, OPA858 seems to…
