Gate oxide tunneling current (Igate) will become the dominant component of leakage in CMOS circuits as the physical oxide thickness (Tox) goes below 15Å. Increasing the value of Tox reduces the leakage at the expense of an increase in delay, and a practical tradeoff between delay and leakage can be achieved by assigning one of the two permissible Tox values to each transistor. In this paper, we...

We examine empirically the performance of multi-level logic minimization tools for a lookup table-based Field-Programmable Gate Array (FPGA) technology. The experiments are conducted by using the university tools misII for combinational logic minimization and mustang for state assignment, and the industrial tools xnfmap for technology mapping and apr for automatic placement and routing. We meas...

the present work with consideratlon to the autoradiographic pictures, suggests that cholinergic receptors are located at the gate of a channel originating from synaptic cleft coming to lie within the muscle fibre. ache molecules stand at the gate of this channel,controlling the entrance of different cholinergic agents. it was report- ••• ed previously that dtc molecules s t.abd ;:.2e the ache r...

the hydrodynamic behavior of approaching flow and the amount of sediment entry into right-angled lateral intakes in diversion dams were investigated using a laboratory channel by experimental measurement and observation. the velocity field upstream of the intake in the main channel and before it at the sluice gate was measured at different elevations of flow at different discharge rates of the ...

data visualization is the process of transforming data, information, and knowledge into visual form, making use of humans’ natural visual capabilities which reveals relationships in data sets that are not evident from the raw data, by using mathematical techniques to reduce the number of dimensions in the data set while preserving the relevant inherent properties. in this paper, we formulated d...

Quantum-dot Cellular Automata (QCA) technology is attractive due to its low power consumption, fast speed and small dimension, therefore, it is a promising alternative to CMOS technology. In QCA, configuration of charges plays the role which is played by current in CMOS. This replacement provides the significant advantages. Additionally, exclusive-or (XOR) gate is a useful building block in man...
