Amplifying the small signals produced by sensors in a low-noise circuit is a very common but difficult problem. Designers will often use an operational amplifier (op amp) with bipolar inputs to ...

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 ...

Sometimes, the need arises fora low-distortion buffer amplifiercapable of handling bipolar signals. Youcan use an op amp or integrated bufferfor these applications, but for more flexibility,a discrete ...

A look at the design of traditional ADC front ends. How to simplify the input drive of CTSD ADCs. Simplifying reference and reference-drive designs. In this article, we will use the terms “sensor” or ...

In this article, we highlight one of the most important architectural traits of new continuous-time sigma-delta (CTSD) precision ADCs: the easy to drive resistive input and reference. The key to ...
