ABSTRACT
In this chapter, the author focuses on the nature of flicker noise, switched-capacitor techniques and noise sampling. He deals with the three main techniques used against flicker noise, which are large-scale excitation, chopping, and correlated double sampling (CDS). Looking at processes generating flicker noise in the time domain instead of the frequency domain gives us much more insight into the nature of flicker noise. The authors have no problems in finding the flickering systems in nature and science; it seems that flicker noise is the rule rather than the exception. It can be observed in systems like vacuum tubes, diodes, transistors, thin films, quartz oscillators, the average seasonal temperature, the annual amount of rainfall, the rate of traffic flow, the loudness and pitch of music, the pressure in lakes, search engine hits on the Internet, and so on. The author provides information on how to simulate flicker noise in MATLAB. He also provides a short annotated literature list.
