Double-gate fully depleted (DGFD) SOI circuits are regarded as the next generation VLSI circuits. This paper investigates the impact of scaling on the demand and challenges of DGFD SOI circuit design for low power and high performance. We study how the added back-gate capacitance affects circuit power and performance; how to tradeoff the enhanced short-channel effect immunity with the added bac...

Silicon-on-insulator ~SOI! has proven to be a viable alternative to traditional bulk silicon for fabrication of complementary metal–oxide–semiconductor devices. However, a number of unusual phenomena with regards to diffusion and segregation of dopants in SOI have yet to be explained. In the present study, SOITEC wafers were thinned to 700 and 1600 Å using oxidation and etching. Ion implantatio...

In this paper, we present: 1) design of a single-rail energy-efficient 64-b Han–Carlson ALU, operating at 482 ps in 1.5 V, 0.18m bulk CMOS; 2) direct port of this ALU to 0.18m partially depleted SOI process; 3) SOI-optimal redesign of the ALU using a novel deep-stack quaternary-tree architecture; 4) margining for max-delay pushout due to reverse body bias in SOI designs; and 5) performance scal...

Silicon substrate losses and non-linearities were the limiting characteristics of Si-based MOSFET technologies to provide low-power and low-cost solutions to the mobile RF device market. Thanks to the trap-rich Silicon-on-Insulator (SOI) substrate invented at UCL and developed in collaboration with the French company SOITEC, RF SOI is becoming a mainstream technology which is implemented in all...

Start of fuel injection and fuel type are two important factors affecting engine performance and exhaust emissions in internal combustion engines. In the present study, a one-dimensional computational fluid dynamics solution with GT-Power software is used to simulate a six-cylinder diesel engine to study the performance and exhaust emissions with different injection timing and alternative fuels...

In this Tutorial, we give a pedagogical introduction to Majorana bound states (MBSs) arising in semiconducting nanostructures. We start by briefly reviewing the well-known Kitaev chain toy model order introduce some of basic properties MBSs before proceeding describe more experimentally relevant platforms. Here, our focus lies on simple `minimal' models where wave functions can be obtained expl...
