Offset on op amp output
I am building an integrator circuit on a breadboard using an LM741 op-amp. Below is the circuit diagram:
The input to the circuit is a 10 kHz signal with a peak to peak of 1 volt (with 0 offset). The ...

Is there a CMOS-based analog compute chip that uses hybrid technology nodes? (e.g. 14 nm for digital part such as SRAM and 28 nm for analog part)
In CMOS-based analog computing, there always are mixture of analog and digital parts.
For example, the computation is performed in analog domain and the storage of on-chip data in performed in digital ...

How to transform resistance between two linear ranges?
This question is motivated by an automotive problem from this question.
In a quad vehicle, in a 12V system, there's a fuel sender with 0-100 ohm range, empty to full. The fuel sender was a part of a ...

Is there any electrical system simple enough to make yourself which has some kind of useful property like radio communication or basic computation? [closed]
I would like to make some kind of primitive system in the direction of a computer, from scratch.
Someone showed me you can use ferromagnets to do some elementary computation; the “states” are the ...

Inverting a (voltage-) transfer function using opamp
If we have a circuit that - given some input voltage \$U\$ - produces an output voltage \$f(U)\$ (where \$f\$ is continuous, monotonic descending), we can construct a new circuit that behaves like the ...
