Lowering power consumption in clock by using globally asynchronous locally synchronous design style

In this paper we propose double gate transistor i.e. FINFETS circuits. It is the substitute of bulk CMOS that mean without any compromise in fabrication process except one or two changes. Actually bulk CMOS suffers high power consumption and high leakage currents .so we implement a various novel circuits i.e FINFETS logic design style in 32nm technology and analyzing various parameters like power dissipation, delay, frequency are observed in this paper. In here we notice that less power consumption in FINFETS when compared to ordinary bulk CMOS. We also check the other submicron technology compared to that this submicron technology got less power consumption.

Design Style

Contemporary digital systems must be based on the “System-on-Chip – SoC” concept. An interesting style for SoC design is the GALS paradigm (Globally Asynchronous, Locally Synchronous), which can be used to implement circuits in FPGAs (Field Programmable Gate Arrays). However the implementation of asynchronous interfaces (asynchronous wrapper – AW) constitutes a major drawback for this kind of devices. Although there is a typical AW design style, which is based on asynchronous controllers providing communication between modules (called ports), port controllers are subject to essentialhazard when implemented in FPGAs. In this context, this paper proposes a new asynchronous GALS wrapper architecture, suitable for implementations in any kind of FPGAs. The proposed port controllers showed to be essential-hazard-free, not needing any special cares in implementation concerning to LUTs choice. Additional advantages of the proposed architecture are: total autonomy that synchronous modules achieve when interacting with the asynchronous wrapper; the ports can be synthesized in the direct mapping style (so without knowledge of asynchronous logic synthesis); and the ports interact with environment in Ib/Ob Mode, not needing a timing analysis. Simulation results show the applicability of the proposed architecture and lead to its practical implementations in FPGAs.

Shim Coil

It is necessary to develop a high homogeneous, low power consumption, high frequency and small-size shim coil for high precision and low-cost atomic spin gyroscope (ASG). To provide the shim coil, a multi-objective optimization design method is proposed. All structural parameters including the wire diameter are optimized. In addition to the homogeneity, the size of optimized coil, especially the axial position and winding number, is restricted to develop the small-size shim coil with low power consumption. The 0-1 linear programming is adopted in the optimal model to conveniently describe winding distributions. The branch and bound algorithm is used to solve this model. Theoretical optimization results show that the homogeneity of the optimized shim coil is several orders of magnitudes better than the same-size solenoid. A simulation experiment is also conducted. Experimental results show that optimization results are verified, and power consumption of the optimized coil is about half of the solenoid when providing the same uniform magnetic field. This indicates that the proposed optimal method is feasible to develop shim coil for ASG.

Design Style

Conventional design practices regard gender as a given precondition defined by femininity and masculinity. To shift these strategies to include non-heteronormative or queer users, queer theory served as a source of inspiration as well as user sensitive design techniques. As a result, a co-design workshop was developed and executed. Participants supported claims that gender scripts in designed artefacts uphold gender norms. The practice did not specify a definition of a queer design style. However, the co-design practice opened up the design process to non-normative gender scripts by unmasking binary gender dichotomies in industrial design.

Halogen Lamps

This work contains analysis of characteristics of automobile lamps by Philips, KOITO, ETI flip chip LEDs, Osram, General Electric (GE), Gtinthebox, OSLAMPledbulbs with H1, H4, H7, H11 caps: luminous flux, luminous efficacy, correlated colour temperature. Characteristics of the studied samples are analysed before the operation of the lamps. The analysis of the calculation results allows us to make a conclusion that the values of correlated colour temperature of halogen lamps are close to the parameters declared by manufacturers. The analysis of the study results has shown that, based on actual values of correlated colour temperature, it is not advisable to use LED lamps in unfavourable weather conditions (such as rain, fog, snow). The results of the study demonstrate that there is a slight dispersion of actual values of luminous flux of halogen lamps by different manufacturers. Maximum variation between values of luminous flux of different lamps does not exceed 14 %. The analysis of the measurement results has shown that actual values of luminous flux of all halogen lamps comply with the mandatory rules specified in the UN/ECE Regulation No. 37 and luminous flux of LED lamps exceeds maximum allowable value by more than 8 %. Luminous efficacy of LED lamps is higher than that of halogen lamps: more than 82 lm/W and lower power consumption. The results of the measurements have shown that power consumption of a LED automobile lamp is lower than that of similar halogen lamps by 3 times and their luminous efficacy is higher by 5 times.
