Designing high-speed circuit boards requires an understanding of signal integrity fundamentals and layout best practices.

This article will explore the differences between single-ended and differential signals and show you how to use each to your advantage in your designs.

We’ll illustrate the importance of setting up functional partitioning in PCB design and give some recommendations on functional partition best practices.

Magnetic coupling is a different animal. A moving electrical charge will generate a magnetic field as a byproduct. The magnetic fields can be quite powerful though their effect drops off rapidly.

There is more than one way to examine how the transmission line reflection coefficient affects your signals.

This article discusses how to reduce capacitive coupling and tips for avoiding crosstalk.

A frequency transformation in filter design lets you generate high pass, bandpass, and bandstop filters from a low pass filter transfer function.

Understand PWM, how to send signals from a microcontroller, and the EMI considerations when planning the duration for digital signals in your PCB design.

Check out this article for how to convert analog signals to PWM signals, as well as some design tips for analog to PWM converters.

Terahertz microcavity resonators are a critical part of on-chip microwave photonics. Here’s how these components will fit into the photonics landscape.

Harmonic motion is more complicated than sinusoidal oscillations. Here’s how complicated oscillations arise in linear and nonlinear circuits.

EMF noise can be reduced with some smart layout decisions. Here’s how you can take control over EMF noise in your design.

A look into S-parameter simulation, and discussion on how these parameters can help maintain signal integrity in RF circuits.

The use of hysteresis with comparators provides increased stability and functionality, which is essential for their proper function in various circuit types.

If you’re using a diode in an AC circuit, you need a small signal model for a diode to describe current and voltage.
