To overcome the limitations of chemical doping in nanometer-scale semiconductor devices, electrostatic doping (ED) is emerging as a broadly investigated alternative to provide regions with a high electron or hole density in a semiconductor device. In this paper, we review various reported ED approaches and related device architectures in different material systems. We highlight the role of metal and...
This paper presents a comparative study of Solar energy fed different DC-DC converters with different speed controllers for Brushless DC motor (BLDC) drive with trapezoidal back electromotive force (emf). Due to the rising energy crunch a Solar Panel has been used to feed the input DC to the converter. Different bridgeless DC-DC Buck-Boost converter has been designed for this work and their efficiency,...
This paper presents a technique to reduce the sub-threshold current in MOSFET by changing the doping profile in the substrate region near the channel. Sub-threshold current is also known as drain leakage current. The size of MOSFET can be reduced but at the cost of increase in leakage of current from drain to source in its stand by mode. This leakage current dissipates power even if the device is...
