It presents a discussion of their performance characteristics and modeling using simple physics-based expressions. The oscillators have been designed in a commercial 0.18 /spl mu/m CMOS technology and the transistors in the VCOs operate from weak to strong inversion modes. They have been tested and found functional with supply voltages from 80 mV up to 1.8 V. Experimental results show that the VCO's power consumption is mainly dynamic for the whole range of supply voltages used and powers down to the nW regime has been achieved. A new and important feature of this VCO is the use of the substrate voltage as an additional control for the frequency tunability. In this way, a new VCO with two voltage controls for its operating frequency has been realized. The detailed experimental results and comparison to calculations are presented and discussed.","PeriodicalId":416680,"journal":{"name":"Proceedings of the Fourth IEEE International Caracas Conference on Devices, Circuits and Systems (Cat.

In particular the TLS EXIN neuron has been employed as it is the only algorithm which solves for the TLS problem in a simple recursive way. The results thus obtained are compared with those obtained with an OLS (ordinary least-square) algorithm to show the substantial equivalence of the two techniques if no noise is present in the measurements. This is the first step for facing up to the estimation of electrical parameters of induction machines in noisy environments (EMC problems), for example in industrial environments.","PeriodicalId":416680,"journal":{"name":"Proceedings of the Fourth IEEE International Caracas Conference on Devices, Circuits and Systems (Cat.

Using the transfer matrix method, and applying the Bloch theorem, the dispersion relation and the analytical expression relating the gain coefficient to the system parameters (such as the period of the structure, contrast of the refractive indices, geometry of the primitive cell, as well as the number of primitive cells creating the photonic crystal) have been derived.

We show that knowing the applied junction voltage, the electrical series resistance and the experimental I/sub th/ vs. T characteristic in pulsed operation is possible to evaluate R/sub th/. The key advantage of the method is that it avoids the measurement in continuous-wave (CW) operation. In particular we consider the case when I/sub th/ versus T characteristics exhibit kinks. To verify our method, CdZnSe, InGaAs, GaN and AlGaAs lasers were analyzed. We show that values obtained in this way agree quite well with the values measured by traditional methods.","PeriodicalId":416680,"journal":{"name":"Proceedings of the Fourth IEEE International Caracas Conference on Devices, Circuits and Systems (Cat.
