Technology scaling reduces device threshold voltages to mitigate speed loss due to scaled supply voltages. This, however, exponentially increases leakage power and adversely affects circuit reliability. In this paper, we will investigate the performance degradation in high-leakage digital circuits. It is shown that deep submicron CMOS technologies lead to 60%−70% degradation in noise-immunity d...

In this paper, we propose a novel adaptive beamforming algorithm with low signal distortion capability and high computational efficiency. The proposed algorithm incorporates the crosstalk-resistant adaptive noise canceller (CTRANC) in place of the usual adaptive interference canceller (AIC). Doing so, a better signal leakage estimate is provided at the adaptive interference canceller input but ...

Multi-threshold CMOS (MTCMOS) is the most widely used circuit technique for suppressing subthreshold leakage currents in idle circuits. When a conventional MTCMOS circuit transitions from SLEEP mode to ACTIVE mode, voltages of power and ground distribution networks are disturbed. Mode transition noise phenomenon in MTCMOS circuits is examined in this chapter. An MTCMOS circuit technique with th...

By optimising the epitaxial layer profile of InGaAs-InAlAs pHEMTs we have demonstrated improved DC and RF performance from a new, low-cost, 1 μm-gate device structure in terms of breakdown voltage, leakage current and output conductance. A simple fabrication process is employed that does not use double-recess or composite-channel structures. No penalty was incurred on cut-off frequency or gain ...

In this paper, we propose the design of low power level-converting retention flip-flop (RFF)using LSSR technique for Zigbee System-onchips (SoCs).The proposed retention flip-flop allows the voltage regulator which generates the core supply voltage (VDD, core) is turned off during the standby mode and thus reduces the standby power and dc current of the Zigbee SoCs. This method is the combinatio...

In this paper low power consumption amplifier is presented. Low power consumption amplifier is versatile demanded in modern technology, modern technology want such type of amplifier which gives low power consumption with less reflection, in this paper presented series and shunt feedback topology with pole zero compensation method for designing of low power consumption amplifier, Today the deman...

low frequency noise (lfn) is ubiquitous in both occupational and general environments. mental performance of subjects exposed to lfn is expected to be impaired. individual characters seem to play a significant role in this process. this study aimed to evaluate the effects of moderate levels of lfn (20–200 hz) on mental performance. fifty-three subjects (in two groups) were exposed to low and fl...

Frequency modulated continuous wave (FMCW) radar systems suffer from permanent leakage due to their continuous operation. Especially in integrated circuits this leads to the well known issue of on-chip leakage due to limited isolation between transmit and receive circuitry. In addition, we investigate short-range (SR) leakage resulting from signal reflections of an unwanted close object located...

When washed yeast cells grown under appropriate conditions were suspended in glucose solution there was a sudden release of alpha-amino nitrogen into the medium. This released material was of low molecular weight, and its composition was closely similar to that of the intracellular free amino acid pool. During the leakage of amino acids, the yeast did not efficiently absorb labeled amino acids ...
