WebThis is a low-frequency phenomenon caused by irregularities in the conduction path and noise due to the bias currents within the transistors. Flicker noise increases inversely with frequency, at a rate of 3 dB per octave, hence it is often referred to as 1/f noise (with “f” referring to frequency). This 1/f noise is still present at higher ...
