In this paper, a new theoretical approach to submicrometer MOSFET subthreshold current modeling is presented. The diffusion and drift currents are calculated, respectively. The effect of velocity overshoot on subthreshold current is investigated. Comparison with MEDICI simulation results verifies the model.

High Q frequency reference devices are essential components in many Integrated circuits. This paper will focus on the Resonant Suspended Gate (RSG) MOSFET. The gate in this structure has been designed to resonate at 38.4MHz. The MOSFET in this device has a retrograde channel to achieve high output current. For this purpose, abrupt retrograde channel and Gaussian retrograde channels have bee...

This paper deals with the modeling of bond graph buck converter systems. The bond graph formalism, which represents a heterogeneous formalism for physical modeling, is used to design a sub-model of a power MOSFET and PiN diode switchers. These bond graph models are based on the device’s electrical elements. The application of these models to a bond graph buck converter permit us to obtain an in...

SOI means Silicon on Insulator. This type of transistors has Silicon-Insulator-Silicon substrate which is different from conventional MOSFET structure where metal layer is used on the top of Insulator [1, . Now a days, the width of the oxide of a MOSFET is reduced from 300nm to 1.2nm and even less with scaling in technology. If it is further reduced, the leakage problems (majorly Sub-threshold ...

According to Moore’s law, the number of transistor embedded on integrated circuit (IC) doubles approximately every two years. Thus, the size of Metal-Oxide-Semiconductor Field Effect Transistor (MOSFET) has to be scaled down as an increase in packing density. In current technology, the size of a transistor has shrunk below 45nm, and it has already reached its physical limit. Any attempt to shri...

In this work, a novel Silicon on Insulator (SOI) MOSFET is proposed and investigated. The drain and source electrode structures are optimized to enhance ON-current while global device temperature and hot carrier injection are decreased. In addition, to create an effective heat passage from channel to outside of the device, a silicon region has embedded in the buried oxide. In order to reduce th...

The buried-oxide in SOI MOSFET inhibits heat dissipation in the Si film and leads to increase in transistor temperature. This paper reports a simple and accurate characterization method for the self-heating effect (SHE) in SOI MOSFET. The ac output conductance at a chosen bias point is measured at several frequencies to determine the thermal resistance ( ) and thermal capacitance ( ) associated...
