The authors present the impact of low frequency substrate noise perturbations on voltage-controlled oscillator (VCO) spectrum. A 5 GHz VCO test-chip is presented; several substrate taps have been placed inside VCO core to measure or to inject noise perturbations. The oscillation frequency sensitivity function of tuning voltage or bias current and spurious side-bands due to injected noise are measured to find out a relation between substrate noise and spectrum purity. Finally, a significant link between such device sensitivity functions and VCO spurs magnitude is demonstrated.","PeriodicalId":359193,"journal":{"name":"Proceedings.

To achieve this goal, it is possible to use a reconfigurable architecture to discharge the processor host from the too complex treatments or for which it is not adapted. The complexity of the treatments entrusted to the coprocessor then varies according to the mode of coupling between this last and the host processor which even influences the cost of communications. This research examines the role of dynamically reconfigurable logic in systems-on-chip (SOC) design. Specifically, in this paper, we carried out the modes of coupling the dynamically configurable cluster DART with a VLIW processor. The implementation of a WCDMA receiver allowed to make qualitative study of various techniques of coupling and to evaluate the performances of the Lx/DART architecture.","PeriodicalId":359193,"journal":{"name":"Proceedings.

The proposed observer is based on the use of neural networks whose their generalisation capacity allows the compensation of the induction machine parameter variations. Considering the enormous algorithmic resources requested by the neural network integration, an optimised architecture of the observer is proposed using CORDIC algorithm.

This network is employed in a digit pattern recognition application. The neural network is trained without any consideration about non-idealities of hardware implementation and then obtained weight parameters are converted to fixed-point bit-string format in order to match hardware implementation. Controlling the number of bits used in this conversion, forces a trade off between accurate operation of the network and size of the hardware. Finding the optimum number of bits, steps are taken for implementation of network.

Some design guidelines are presented to improve integration of learning algorithm into the hardware. By using them, it is possible to design high performance neural networks, which are capable of handling a rapidly-conversing learning algorithm in analog chips. The analytical approach developed in this work provides more insight towards tuning of a reliable design. Our experimental results prove that this approach performs above the conventional fixed learning rate approach, and is almost comparable to the ideal gradient based adaptive approach.","PeriodicalId":359193,"journal":{"name":"Proceedings.

The SIGMASPACE is designed as a hybrid system including many gateways on the wired communication bus and master slave communication fulfilling the EN54 standards. The SiRoute system is based on a multi-hop mesh network that allows low battery power consumption, high ranges in buildings independently of structures and reaction times according to EN 50131-1. The wireless communication is performed in an exclusive frequency band for short-range devices by 868 MHz with regulated effective radiated powers and transmission duration (duty cycle).","PeriodicalId":359193,"journal":{"name":"Proceedings.
