Generally speaking, noise is any electrical phenomenon that is unwelcome in an electrical system. This article is the first of a three-part series about noise in the signal chain. Here we focus on the internal sources of noise found in all semiconductor devices: thermal, shot, avalanche, flicker, and popcorn noise. A procedure to estimate noise voltage will be given along with an example. Finally, a free calculator is presented that aids in estimating noise under conditions that are not specified in a device data sheet.

Managing Noise in the Signal Chain, Part 2: Noise and Distortion in Data Converters;
Data converters incorporate the common semiconductor noise sources such as, shot, avalanche, flicker, and popcorn noise. In addition, real data converter systems have errors that include quantisation, clock jitter, channel linearity, and bandwidth. Practical use of industry data sheets demonstrated to determine what system specifications can be achieved. Design tools that aid in the analysis of these parameters, and constructive ways to control and reduce other system noise elements are presented.

Selecting the Best Data Converter for a Given Noise Budget: Part 3;
The practical use of industry data sheets is demonstrated to determine what system specifications can be achieved, in the presence of system errors, such as data-converter quantisation, clock jitter, channel nonlinearity, and input- and output-referred noise. Design tools that aid in the analysis of these parameters, and constructive ways to control and reduce other system noise elements are highlighted.
