PCB track widths for optimized layout for operational amplifiers
When designing a PCB track, its width, length, and stack-up can introduce inherent inductance and capacitance. These parasitic elements can significantly impact the performance of sensitive circuits, ...

Is it possible to match impedance "with lower parasitic capacitance", or is parasitic capacitance itself a part of impedance
Parasitic capacitance makes the signal rise and fall slower, so I want it be as small as possible, but when I try to adjust parameters in Altium Designer (e.g. trace gap of a differential pair) for a ...

Investigating the effect of PCB layout parasitic in an op-amp amplifier by simulation
Would you please let me know what components I should add to my schematic as result of PCB parasitic to make my simulation more accurate?
As an example, the following image shows an amplifier ...

Can parasitic capacitances be decoupled?
I was working with some IC that has a bus that is really sensitive to trace capacitance and cannot be loaded with more than 8.5 pF.
I have to bifurcate the trace to an ADC because I need to see what ...

How to extract parasitic capacitance caused by PCB layout? [closed]
I'm working on a precision DC measurement PCB design based on the capacitance-integration method. The key element integration capacitor is quite precise. However, due to my specific PCB layout design, ...

Thin Film Resistors, Deposition On One Side, Parasitic Capacitance if Resistor is placed such that Deposition next to PCB Ground Plane
I have a question for all high frequency and RF electrical engineers.
Thin film resistors have a vapor deposition of resistive material on one face of the component. Let's presume that the resistor ...

Capacitances in a PMOS transistor: what about the n-well?
So I'm studying MOS transistors and came across the topic of capacitances between various terminals/contacts, including the bulk terminal. These capacitances are due to lateral diffusion as a ...

Resistor-Capacitor-Resistor configuration and layout differences
How you can explain the R-C-R configuration? Goertz zobel
link to the web-article
This looks to be used as a RF audio cable terminating, I suppose.
Which can be the electro-technical difference of ...

how to isolate coupled noise source in parasitic capacitance in high voltage pcb design?
I'm new designing a high/medium voltage (V <=10kV) with low voltage and low current (10mA). There will be only a few HV relays. Their coils will be triggered by LV.
I have read some literature ...

PCB trace length
I have some doubts. At the output of my phono preamp there are very big coupling capacitors and i didn't have choice (i think so) - i had to make long traces with output signal. The trace width is 1....
