This paper outlines improvements required in the modal decomposition equivalent circuit modelling (MDECM) method to simulate complex periodic structures at high frequencies as THz. It discusses initial approximations used by the method and whether they should be retained. Finally, in comparing the results of Modal Decomposition Equivalent Circuit Method (MDECM) to commercial computational electromagnetic...
The Tektronix CT2 current probe is used to acquire more accurate Human Body Model waveforms with 0-ohm and 500 ohm tester loads than a CT1, owing to the CT2's low-frequency performance. The integrals and centroids of these waveforms then readily yield precise values of tester circuit elements and effective socket capacitance. Expressions are derived for effective socket capacitance resulting from...
The authors investigated an EMC macro-model of the CMOS logic inverter gate, named LECCS-I/O that consists of linear equivalent circuit and current sources. This paper modifies the macro-model by adding another current source to express the short-circuit current in the inverter. The macro-model was determined from SPICE calculations of impedance and power current by using a device model of an inverter...
Current mode (CM) scheme provides suitable alternative for the high speed on-chip interconnect signaling. This paper presents a energy-delay optimization methodology for the current-mode (CM) signaling scheme. Optimization for the CM circuits for on-chip interconnects requires a joint optimization of driver and receiver device sizes, as their parameters which affect the energy-delay performance depend...
In this work, it is shown that the previously reported and accepted equivalent circuit models of resonant type left-handed lines, either loaded with split ring resonators (SRRs), or with complementary split ring resonators (CSRRs), need a revision in order to properly account for the different elements of the structures and to accurately describe their behavior. The main relevant conclusion and novelty...
The next generation of wireless communication is a ubiquitous radio system concept, providing wireless access from short-range to wide-area, with one single reconfigurable and adaptive system for all envisaged radio environments. This paper presents the design approach of RCO (reconfigurable concurrent oscillator) that simultaneously generates two or more signals of different frequencies that eliminate...
A thin film optoelectric transformer consisting of a p-n junction photocell (500??500 ??m2) and a multilayer spiral coil transformer (1.4??1.4 mm2), monolithically fabricated on a Si substrate, is proposed, and its fundamental characteristics are described. The optical power from a layer diode (LD) is converted into electric power by the photocell, and the photocurrent is then converted into an output...
