Ways to get around amplification limited by op amp GBW?

I'm working on a project that requires me to amplify 70 pA to read out at 10 V (the digitizer I'm using to collect data has a range of 0 to 10 V readout). On top of this, I need to sample my voltage ...

Schematics of photodiode BPW34 interfacing with an ADC ESP32

I am designing a circuit that uses a BPW34 photodiode for visible light communication. The transmission distance is about 5-6 m, and the transmission frequency is only about 1-10 kHz. I have consulted ...

LTSpice multiple input source noise analysis

In my schematic, I have two input differential current source and I want to simulate the output noise of the system. However, the LTSpice noise simulation only allows me to put one input source in the ...

Photodiode amplifier with cascaded amplifier

I have designed a photodiode circuit using the OSD35-5T photodiode from Centronic. I am using the LTC 2054HV as a transimpedance amplifier (TIA) and the LTC2051HV (dual opamp) as the next stage ...

Why would a photodiode with an op-amp be very linear?

I read here mentioned The configuration in Figure 1a creates a very linear response in terms of the irradiance of the light source. Would this configuration of photodiode not be linear? Why? The ...
