How can I estimate blocking window distance in an sCMOS sensor setup?
I am trying to establish an appropriate distance between a spectrograph output window and a CMOS sensor.
The spectrograph creates a focused image on the CMOS sensor but I am trying to restrict the light as the initial pixels are capturing light of…

Can an active pixel (CMOS) image sensor work without the lenses?
Hello I was wondering if a CMOS image sensor will work without its lenses, I want to install a pinhole instead of the lenses, I want to simulate a sun sensor with the CMOS image sensor of an ESP32-CAM, something like this:
As you see, the CMOS image…

Switching speed of a (nano) transistor
Usually, the frequency of a computer's CPU is expressed in GHz.
But does this mean that the individual transistors etched on the chip also switch on and off billions of times per second? Or are the high frequencies of CPUs achieved thanks to some…

calculating drain current
I am doing a practice question where I'm supposed to find a drain current for a figure, shown in the light blue box in the picture below (along with my calculations).
The red writing is the equation I've gotten by applying KCL.
In order to find Id…

Floating node in 4T CMOS camera pixel
I know how a 3 Transistor CMOS camera pixel works. As I understand, 4T CMOS pixels have one additional transistor that connects the photodiode to a so-called floating node.
What is that floating node and what is it good for? Seems like a storage for…
