photodiode

I'm having trouble finding a theoretical explanation about the transconductance photodiode behavior, the materials I find on the internet they talk about the connections, but not the behavior, in case someone could insert material or write here with the source please.

Hi, I created simple circuit with photodiode for pulse oximeter. As you can see I use opamp in single supply mode. After removing DC offset I put 1V offset on non-inverting input on opamp. Then RC filter is connected to grond. Is everyting correct? I wonder if I should connect REF on ADC to...

Greetings, I am stuck in finding the component as shown in the picture attached. This component is used in photodiode circuits. I am a software engineer that has basic electronic knowledge and needs to make integrate the circuit so that I can view all the light values on my application. I hope...

Hello, I am hoping that someone will be able to direct me towards the appropriate piece of hardware to purchase. I am a cognitive neuroscientist, hoping to stimulate a specific area of the brain using Transcranial Magnetic Stimulation. The onset of stimulation needs to be precise (~100ms) and...

Hello, My name is Dragos.I am beginner in simulation S.P.I.C.E.. and I use the simulator Micro-CAP 12, to simulate an electric schematic. I want to simulate the photodiode PIN InGaAs IG17-series,here I used an an electric equivalent model of working of photodiode and I want to monitor...

Hello, My name is Dragos.I am beginner in simulation S.P.I.C.E.. and I use the simulator Micro-CAP 12, to simulate an electric schematic. I want to simulate the phototransistor PIN InGaAs IG17-series and to monitor grafically the rectangular electrical impulse, at an amplitude of a few volts...

I am a beginner PSPICE, in simulation electrical and electronics circuits. I want to simulate a schematic with the program Micro-CAP 12. I want to look for some graphics from a photodiode PIN which is a InGaAs Photodiode IG22-Series, I want to monitor follow parameters: responsivity (A/W) vs...

Hello everyone, I am currently working in a photodiode circuit which creates AC voltage -280mV to +80mV. I need to amplify the circuit using transimpedance amplifier. The output voltage range must be ±10V. How to select a suitable OPamp for this purpose? What factors must be considered? How is...
