This article reports on the investigation and optimization of cryogenic noise mechanisms in InGaAs metamorphic high-electron-mobility transistors (mHEMTs). HEMT technologies with a gate length 100, 50, 35 nm are characterized both under room temperature conditions. Furthermore, two additional technology variations 50-nm investigated to decompose different HEMTs. Therefore, extended Ku-band low-...

background: acoustic noise is one of the universal pollutants of modern society. although the high level of noise adverse effects on human hearing has been known for many years, non-auditory effects of noise such as effects on cognition, learning, memory and reading, especially on children, have been less considered. factors which have negative impact on these features can also have a negative ...

Ultra-low power applications often require several kb of embedded memory and are typically operated at the lowest possible operating voltage (VDD) to minimize both dynamic and static power consumption. Embedded memories can easily dominate the overall silicon area of these systems, and their leakage currents often dominate the total power consumption. Gain-cell based embedded DRAM arrays provid...

In recent years, many leakage-resilient schemes have been published. These schemes guarantee security against side-channel attacks given bounded leakage of the underlying primitive. However, it is a challenging task to reliably determine these leakage bounds from physical properties. In this work, we present a novel approach to find reliable leakage bounds for side channels of cryptographic imp...

In multi-cast scenario, all desired users are divided into K groups. Each group receives its own individual confidential message stream. Eavesdropper group aims to intercept K confidential-message streams. To achieve a secure transmission, two secure schemes are proposed: maximum group receive power plus null-space (NS) projection (Max-GRP plus NSP) and leakage. The former obtains its precoding...

Due to the non-periodic nature of noise, the steady state response of a dynamic system to a periodic input is still subject to noise transients (noise leakage errors). For lightly damped systems these noise transients (significantly) increase the variance of frequency response function (FRF) measurements [1]. This paper presents a method for suppressing the noise transients in FRF measurements ...

An alternative method for power spectral density (PSD) estimation--the Daniell method--is revisited and compared to the most prevalent method used in the field of atomic force microscopy for quantifying cantilever thermal motion--the Bartlett method. Both methods are shown to underestimate the Q factor of a simple harmonic oscillator (SHO) by a predictable, and therefore correctable, amount in ...

This paper provide new low power solutions for Very Large Scale Integration (VLSI) designers. Especially, we focus on leakage power reduction. Although leakage power was negligible at 0.18μ technology and in nano scale technology, such as 0.07μ, leakage power is almost equal to dynamic power consumption. This paper presents heretofore unexplored methods for low-power VLSI design. In particular,...

The capillary action of saliva occurs in the crevices around and between teeth and around dental restorations. Marginal leakage and denture retention caused by a thin film of saliva are aspects of capillary phenomena. Liquids in capillaries isolated from a reservoir showed an increase in surface tension and lower vapor pressure. The strength of thin films of human saliva was independent of ambi...
