1/f Noise Modeling
The 1/f noise or Flicker noise is an important noise source generated at low frequencies. Accurate measurement and modeling of 1/f noise for deep sub-micron CMOS, BJT, FET and HBT devices as well as RF passive components are critical to RF circuit designs.
For example, the 1/f noise shows up as phase noise in an oscillator design where it mixes with the oscillation frequency, causing the oscillator to become unstable. A noisy local oscillator (LO)signal can degrade a receiver's useful dynamic range and selectivity, making it difficult to recover a signal buried in the noise.
