Noise Parameter Modeling of HEMTs and Nanometer-Scale CMOS Transistors

Closed-form expressions for the gateleakage resistance, Rp and its associated noise temperature, Tp, are presented. Tp represents the noise contribution caused by the gate-current Ig. Both Rp and Tp are expressed as functions of the measured noise parameters Rn, Fmin and Zopt. We present both frequency independent expressions and frequency dependent equations and discuss their accuracy. Unique ...

Modeling of Bias Dependent Fluctuations of Flicker Noise of MOSFETs

Drain and gate bias dependent fluctuations of flicker noise of MOSFETs are explained in terms of carrier concentration distributions in a MOSFET channel. A proposed model well describes the increase of the fluctuation in the saturation region of operation. In addition, the gate bias dependence of the fluctuation in the saturation region can also be calculated using the model. Our model predicts...

Flicker Noise Characteristics in GaAs MOSFETs

This study reports the flicker noise characteristics in GaAs-based MOSFETs for the first time. With the improvement in Ga 2 O 3 (Gd 2 O 3) insulators, GaAs MOSFETs reveal the possibility for high-speed and high-power applications, resulting from an electronic mobility that is about five times greater than that in Si, and the advantage of semi-insulating substrate. The DC and RF characteristics ...

DC modeling and the source of flicker noise in passivated carbon nanotube transistors.

DC and intrinsic low-frequency noise properties of p-channel depletion-mode carbon nanotube field effect transistors (CNT-FETs) are investigated. To characterize the intrinsic noise properties, a thin atomic layer deposited (ALD) HfO(2) gate dielectric is used as a passivation layer to isolate CNT-FETs from environmental factors. The ALD HfO(2) gate dielectric in these high-performance top-gate...

Hydrodynamic Modeling of AlGaN/GaN HEMTs

For the needs of high electron mobility transistors (HEMTs) optimization a reliable software simulation tool is required. Due to the high electric field in the device channel a hydrodynamic approach is used to properly model the electron transport. We modify an existing hydrodynamic mobility model in order to achieve a better agreement with Monte Carlo (MC) simulation data and measured DC and A...
