(Editor's Note: There are links to the previous parts of this series at the end, below the author's biography.) In the first article of this series, “Operational Amplifier–The Basic Building Block” ...

As an applications engineer for a company making configurable analog products, I occasionally get asked to provide a design to integrate a signal before digitizing it. In many cases, the people doing ...

Step-by-step approach to building a CTSD modulator loop. Introducing the analog accumulator. A closer look at oversampling and noise shaping. The clock sensitivity of CTSD ADCs. 1. A closed-loop op ...

A class-D puts out a pulse-width modulated (PWM) signal instead of the linear signal that is typical in class-AB amplifiers. The PWM signal contains the audio signal and the PWM switching frequency ...

This article will explain continuous-time sigma-delta (CTSD) ADC technology in a less traditional approach, enabling signal chain designers toenvision a new class of easy to use precision ADC ...
