Smart power ICs, which monolithically integrate low-loss power devices and control circuitry, have attracted much attention in a wide variety of applications [1], [2]. Commonly used smart power devices are the LDMOS and LIGBT implemented in bulk silicon or SOI (Silicon on Insulator). One of the key issues in the realization of such ‘smart power’ technology is the isolation of power devices and ...

Background: Several studies investigated the association of ACE I/D polymorphism with the risk and severity of COVID-19 infection.  However, the information in each of the published studies is limited, and the results were inconsistent or even contradictory. Accordingly, this meta-analysis evaluated the association between the ACE I/D polymorphism and COVID-19 susceptibility and severity. Metho...

objective: childhood infectious diseases are one of the most known environmental pathogenic causes of childhood asthma. the high prevalence of both helicobacter pylori infection and asthma in our country prompted us to assess anyprobable as- sociation between them in childhood. methods: this cross-sectional study recruited 196 children aged 6 to 12 years old comprising 98 asthmatic (case group)...

In this paper an introduction to substrate noise in silicon on insulator (SOI) is given. Differences between substrate noise coupling in conventional bulk CMOS and SOI CMOS are discussed and analyzed by simulations. The efficiency of common substrate noise reduction methods are also analyzed. Simulation results show that the advantage of the substrate isolation in SOI is only valid up to a freq...

SOI technology for state of the art CMOS technology is rapidly approaching maturity. PD-SOI device design has the advantage of easier manufacturing but requires more sophisticated device and circuit design to reduce the effects of the floating-body. FD-SOI device design potentially has the advantage of no floating-body effects but requires very thin silicon films making manufacturing more chall...

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...
