Noise can be defined as any unwanted signal in an electronic system. Noise is responsible for reducing the quality of audio signals or introducing errors into precision measurements. Board- and system-level electrical design engineers are interested in determining the worst case noise they can expect in their design, design methods for reducing noise, and measurement techniques to accurately verify their design. Intrinsic and extrinsic noise are the two fundamental types of noise that affect electrical circuits. Extrinsic noise is generated by external sources. Digital switching, 60 Hz noise, and power supply switching are common examples of extrinsic noise. Intrinsic noise is generated by the circuit element itself. Broadband noise, thermal noise, and flicker noise are the most common examples of intrinsic noise. This book describes how to predict the level of intrinsic noise in a circuit with calculations, and using Spice simulations. Noise measurement techniques are also discussed
