In order to design oscillators and switches phase noise characteristic is the key to obtain high quality frequency spectrums. Since the phase noise is directly affected by the 1/f noise of transistors in the circuit, 1/f noise measurement and modeling are important. This paper describes 1/f noise measurement, frequency and bias dependent flicker noise model, and noise parameter extraction method of MOSFET's. Also, for MOSFET's geometry dependencies of drain current 1/f noise are analyzed and modeled. The model has been verified by measuring the noise current spectral density of MOSFET's in two different process devices.
