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 ...

Op-amp schematic connection questions and DC biasing
In the first stage the signal is converted to single-ended, and it is amplified using a digital potentiometer in the second stage to be able to change the gain with a microcontroller.
In the last ...

Minimizing noise with single-ended opamps
Opamps often get used with one input at a DC voltage, usually the main ground per the standard inverting amplifier example:
For low noise, a BJT input stage like OPA1611's is often chosen for the ...

Single-ended or differential for very high frequency?
When reading the ADF4371 evb datasheet,
I realized that 16-32 GHz output uses only single-ended but all other outputs use differential output. Doesn't it mean for very high frequency the single-ended ...

Differential and single ended crosstalk and clearance
I know that there can be crosstalk between differential pairs (and you need at least a few lengths equal to the diff pair between diff pairs, usually 3 or more diff pair widths).
What is the ...

DC-coupled wide-bandwidth differential to single-ended conversion
I'm designing a circuit that produces differential signal outputs in the frequency range from DC to about 2 GHz. This differential signal will be driven by an FDA (probably LMH6401 or LMH5401). I'd ...
