Using input-referred noise to improve analog-to-digital converter resolution

All analog-to-digital converters (ADCs) have a certain amount ofinput-referred noise. In most cases,less input noise is better. There are some cases, however, where inputnoise can actually be helpful ...

What is a DAC, and why would you need one?

If you’ve ever listened to an MP3, watched a movie on Netflix, or jumped on a Zoom call, you’ve used a DAC. Digital-to-analog converters (or DACs for short) are the unsung heroes of the digital audio ...
