The aim of this paper is to present mathematical model which can be used to predict influence of ceramic coolers geometry on their cooling abilities. The model was derived using Design of the Experiment methodology.
In this article, an analog fully programmable membership function generator (MFG) is presented. It is capable of generating Gaussian, Triangular and Trapezoidal shapes as well as S or Z shapes. For omitting noise disturbances, differential structures are utilized in input and output stages which are in voltage mode and current mode, respectively. In contrast with conventional MFGs which are controlled...
In this paper an extension of thermal influence coefficients method to frequency domain has been presented. The method allowed the steady-state analysis of three-dimensional heat flow in multilayered structures. The presented modelling is based on Fourier and Hankel transforms, two-port network theory and correction coefficients for close-area distances, allowing emulation of finite heat sources by...
Robustness of modern ICs during system assembly and normal operation requires that protection circuits are built-in to prevent damage to internal circuit elements due to Electrostatic Discharge events (ESD), which can inject substantial energy into the chip. ESD protection as well as protection against other damaging events, such as latchup, is highly dependent on chip architecture and circuit design,...
A 2D physics-based model for short-channel junctionless double gate (DG) MOSFETs is presented. From a closed-form solution for the 2D potential we derive explicit equations for the calculation of threshold voltage VT and subthreshold slope S. A unified charge model valid for all operating regimes is developed by using Lambert's W-function, and a standard smoothing function for the transition between...
A novel high speed and tunable transconductor suitable for analog and mixed-signal fuzzy circuits operating in current mode and a high linear MIN circuit are proposed. Using this OTA, we construct are high speed Gaussian and trapezoidal-shaped fuzzifier and implement S-shaped and Z-shaped function with all parameters (slop, width, and position) independently and continuously tunable, and excellent...
