WebFlicker noise, well known as 1/f noise, has an amplitude that changes over frequency. The fl icker noise is random in nature and is caused by defects in the semiconductor lattice structure, as a result of combination and recombination of carriers within the crystal. Unlike the thermal and shot noise, fl icker noise decreases with frequency.
