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 ...

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 ...
