There are two dynamics issues in vision chips: (i) The temporal dynamics issue due to the parasitic capacitors in a CMOS chip, and (ii) the spatial dynamics issue due to the regular array of processing elements in a chip. These issues are discussed in [1]–[3] for the resistor network with only associated parasitic capacitances. However, in this paper we consider also parasitic inductances as we...

A numerical procedure for extracting parasitic circuit elements using a quasi-static field solver, as part of the Virtual Test Bed (VTB), is discussed. The parasitic inductance and capacitance values obtained from the model are compared to measured values from a low-inductance Power Electronic Building Block (PEBB) module, designed and constructed at Harris Semiconductor.

in this paper, two new quadrilateral elements are formulated to solve plane problems. low sensitivity to geometric distortion, no parasitic shear error, rotational invariance, and satisfying the felippa pure bending test are characteristics of these suggested elements. one proposed element is formulated by establishing equilibrium equations for the second-order strain field. the other suggested...

In this paper, we propose a novel microstrip antenna for operating over a three frequency bands, covering the 2.4/5.2/5.8 GHz WLAN and 2.5/3.5/5.5GHz WiMAX bands. The proposed antenna occupies an area of 30 mm  40mm, when printed on FR4 substrate (εr=4.4, h=0.8mm). The antenna comprises of a triangular patch section, L-shaped parasitic elements on the edges of triangular patch and a 50Ω micros...

These impedance conditions correspond to the class F operating condition, the ideal voltage and current shapes for which are shown in Figure 1. Here a sum of odd harmonics produces a square voltage waveform and a sum of even harmonics approximates a half-sinusoidal current shape. In reality, both extrinsic and intrinsic transistor parasitic elements have a substantial effect on the efficiency, ...

With the rapid development in wireless communication systems, the multiple separated frequency band antennas have become one of the most important circuit elements and attracted much interest. In this paper firstly a floral shaped patch antenna is designed to resonate at multiple bands by introducing four slits on all the four sides of a rectangular shaped patch. Later on by adding four differe...

We propose here a time-domain shooting algorithm for calculating the steady-state responses of nonlinear RF circuits containing parasitic elements that is based on both a modified Newton and a secant methods. Bipolar transistors and MOSFETs in ICs have small parasitic capacitors among their terminals. We can not neglect them because they will gives large effects to the shooting algorithm at the...
