The dosimetry of very small electron fields can be challenging due to relative shifts in percent depth-dose curves, including the location of dmax, and lack of lateral electronic equilibrium in an ion chamber when placed in the beam. Conventionally a small parallel plate chamber or film is utilized to perform small field electron beam dosimetry. Since modern radiotherapy departments are becomin...

This paper presents a method of thermal balancing for monolithic power integrated circuits (ICs). An on-chip temperature monitoring sensor that consists of a poly resistor strip in each of multiple parallel MOSFET banks is developed. A temperature-to-frequency converter (TFC) is proposed to quantize on-chip temperature. A pulse-width-modulation (PWM) methodology is developed to balance the chan...

In the present paper we have done a comparative analysis of Dual Gate MOSFET having split gate architecture and conventional Dual Gate MOSFET architecture. Simulations have been performed using SILVACO-ATLAS tool, which shows significant improvement in characteristic of split gate architecture in comparison to the conventional structure. The split gate architecture consist two different materia...

1.1 CMOS downscaling to DG-MOSFETs As device scaling aggressively continues down to sub-32nm scale, MOSFETs built on Silicon on Insulator (SOI) substrates with ultra-thin channels and precisely engineered source/drain contacts are required to replace conventional bulk devices (Celler & Cristoloveanu, 2009). Such SOI MOSFETs are built on top of an insulation (SiO2) layer, reducing the coupling c...

Measurement of the lateral profile of the dose distribution across a narrow x-ray microbeam requires a dosimeter with a micron resolution. We investigated the use of a MOSFET dosimeter in an "edge-on" orientation with the gate insulating oxide layer parallel to the direction of the beam. We compared results using this technique to Gafchromic film measurements of a 200 micrometer wide planar x-r...

Short-channel devices are preferred for realizing millimetre circuits, but these are affected by the shortchannel effects (SCE). Multi-Gate (MG) MOSFET is found to be an alternative to overcome this drawback. In this paper, study and analysis of DC and AC parameters of MG MOSFETs have been attempted and small signal gain (y21) of multi-gate structure is analytically derived. Design of low noise...

It is vital to measure the dose to the patient's skin during the treatment of total skin electron therapy (TSET). Purpose of the present study is to determine the benefits of using One-Dose MOSFET detectors in the treatment of mycosis fungiodes with TSET protocol. During the study six patients with advanced stage of (MF) were treated by (TSET) using a six dual-field Stanford technique. One-Dose...

The sub-threshold R-MOSFET resistor structure which enables tuning range extension below the threshold voltage in the MOSFET with moderate to weak inversion operation is analyzed in detail. The principal operation of the sub-threshold resistor is briefly described. The analysis of its characteristic based on approximations of a general MOS equation valid for all regions is given along with disc...

In this paper, a new design of three transistor XOR gate is proposed using Independent Driven Double Gate MOSFET to achieve ultra-low power in sub threshold conduction. The proposed design has been compared with the three transistor XOR implemented using Symmetrical Driven Double Gate MOSFET in sub threshold region.
