R&D management practices typically conceptualize complex product innovation as a Stage-Gate process whereby novel concepts are matured through a succession of development stages and progressively winnowed down at each sequential gate. This view implicitly assumes that maturity is a monotonically increasing function of the technology, and that partially matured technologies can be restored from ...

objective: different categories are available for estimating of radiation dose. radioisotopes with the same energy and almost the same physical properties have similar effects. monte carlo technique is a computerized method based on mathematical simulation of physical processes. the main purpose of this study is to show that beta particles are not able to penetrate deep into the water. also dif...

Conditional Reactive Hierarchical Memory(CRHM) and its dynamic sensory gating system are proposed. CRHM has the hierarchical intelligent structure and has the efficient mechanisms of an acquisition stage, a retention stage and a retrieval stage for the memory process. The sensory gating system is designed for the adaptive perception in a retrieval stage. The sensory gate is tuned in to regulate...

Alternative wide band Low-Noise Amplifier (LNA) topologies to be used for highly integrated CMOS transceivers are investigated. A methodology that systematically generates all the LNA topology options with 2 Voltage Controlled Current Sources (VCCS) is presented. Next to wellknown circuits such as the common gate stage and shunt series feedback common source stage, 2 alternative LNA topology ar...

This brief presents a reconfigurable fast filter bank (RFFB) with less gate counts for wireless communication applications such as spectrum sensing and channelization. RFFB offers fine control over subband bandwidth without any reimplementation. This is accomplished with an improved modified frequency transformation-based variable digital filter (MFTVDF) at the first stage of the multistage imp...

This brief presents a reconfigurable fast filter bank (RFFB) with less gate counts for wireless communication applications such as spectrum sensing and channelization. This is designed with an improved modified frequency transformation-based variable digital filter (MFTVDF) at the first stage of the multistage implementation. The low-pass MFT-VDF offers unabridged control over the cutoff freque...

n this paper the Low Noise Amplifier (LNA) operating with a centre frequency of 1.5 GHz is designed using 0.25μm CMOS technology. The Designed FB-LNA uses a stagger-tuning technique. A current-reused architecture is employed to decrease the power consumption using an input common-gate stage, common-gate lownoise amplifier (CGLNA) exhibits a relatively high noise figure (NF) at low operating fre...

Low voltage (LV) analog circuit design techniques are addressed in this tutorial. In particular, (i) technology considerations; (ii) transistor model capable to provide performance and power tradeoffs; (iii) low voltage implementation techniques capable to reduce the power supply requirements, such as bulk-driven, floating-gate, and self-cascode MOSFETs; (iv) basic LV building blocks; (v) multi...
