The circuits presented here use ananalog switch—such as a DG419or one-third of a CD4053—to combinean analog signal with a standard PWMsignal. Most microcontrollers can easilygenerate the PWM signal.

If you simulate circuits that include not only analog, but also digital or switching/PWM aspects, then you know that traditional “AC” or frequency-domain analysis cannot be used for these designs.

Analog and mixed-signal design are an essential part of modern electronics. At Agile Analog, we often hear that digital design engineers find integrating analog components can be a daunting task. So, ...

Why didn’t they do this sooner? That’s the question some embedded engineers designing with microcontrollers (MCUs) are asking about the idea of adding analog signal-chain components in MCUs. With ...

DESIGN VIEW is the summary of the complete DESIGN SOLUTION contributed article, which begins on Page 2. There are many ways, and just as many opinions on the best method, to configure grounds for ADCs ...

This article explores key mixed-signal applications, highlighting the difference between signal-path faults and rail-driven ...

The distinction between analog and digital signals is very simple, but it can still be a challenge to wrap one's mind around the concepts that define the two systems. Just when you think you've got it ...
