Q.  Low frequency noise is
- Published on 15 Oct 15

a. Transit time noise
b. Flicker noise
c. Shot noise
d. None of the above

ANSWER: Flicker noise
 
With decrease in the frequency, the power spectral density of the flicker noise increases. It is generated due to fluctuations in the density of the carrier that increases the conductivity of the material. Therefore, there is a voltage drop during the flow of current. The flicker noise is considerable at low frequencies (below a few KHz).
