Is it safe to have power lines gently squeezed against BMS module?
3x 18650 batteries in series inside their compartment. If I want to include a BMS module then due to limitations on available space, my only option is to have the power lines gently squeezed against ...

What should be the minimum distance between SDA (data) and SCL (clock) traces in this case?
For a PCB design I will use the upper layer for traces and bottom for the ground plane. I have I2C lines(SDA and SCL) going from an MCU pins to a sensor pads as you see below: I2C SDA and SCL are ...

When compared to single-ended signals, do differential signals actually offer better EMI protection?
I'm looking for clarification on whether differential signals actually offer benefits with regards to EMI protection versus single-ended signals. Here is my current understanding (feel free to make ...

Why is the core resistance modeled as 2*Rp and capacitance as Cp/2 in a common-mode choke?
I directed my attention to a paper regarding the modeling of common-mode chokes. Within this paper, the authors structured the circuit in such a manner that they designated the core resistance (...

How can I calculate the amount of crosstalk/parasitic capacitance between two plates with different voltages across them?
I will preface this with the fact that I am a nuclear engineering student, not electrical, but I am working on a senior design project that might as well be an electrical engineering project. We don't ...

How to dampen/reduce oscillations from crosstalk in encoder signals
I have two encoders that emit A/B signals for a total of 4 wires. Not sure if this will be relevant but these encoders are not the same and have different output impedances and rise/fall time. I also ...

How to properly model biased photodiode circuit with cross-talk
The overall goal is the following: I need a board with two photodiodes, each with a bias tee (cutoff around 70 MHz) connected to it, for a total of 4 outputs. The photodiodes will see short pulses, ...

Cross talk within IC package
I have learnt that on the PCB, the signal tracks must be a certain distance apart to minimize cross talk. This makes sense this we must reduce the electric and magnetic field coupling across to ...

Why is inductive coupling negligible at low frequencies?
I've been reading some papers from the early telephone era. I see a lot of statements thrown around like "crosstalk at low or voice frequencies, where inductive coupling is negligible..." ...

What is the right way to avoid crosstalk of different analog channels?
I'm designning a board including three channels of light pulse detection, each channel contains TIA and FDA: During test, I found large pulse on one channel will cause some crosstalk on other two ...

Inductive crosstalk mechanism for 2 lines that run parallel on the same layer
According to Faraday's law, changing magnetic field lines that penetrates the victim line must create voltage on the victim line, but if we imagine, we see lines are orthogonal to the victim trace ...

How can I avoid this crosstalk issue?
I have cutout a piece of my PCB that generates the crosstalk (I measured with multimeter.) In the middle I have a 3.3 V boost/buck converter which generates power for my ESP32. On the left there is a ...

High-speed PCB crosstalk, inductive vs capacitive
I know that at the time of crosstalk Capacitive as well as inductive currents generate voltage drops on the victim line over termination resistors. I have three questions. 1)Why inductive crosstalk ...

Need help with circuit for buffering DAC output for low voltage/ moderate current application near 25 Hz, without crosstalk
I have some custom linear force probes I need to be able to control for a lab experiment. They're essentially just a big coil combined with a spring that deflects up or down based on the voltage put ...
