Abstract:

As the dimensions of ultralarge-scale-integration devices scale to smaller feature sizes and larger die dimensions, the resistance-capacitance (RC) delay of the metal interconnect will increasingly limit the performance of high-speed logic chips. This is because the transistor capacitance and resistance both scale to lower values as the feature size is reduced, while both the line-to-line capacitance and resistance of the metal-interconnect lines increase as their dimensions decrease. For interconnects 5-mm long, the crossover feature size at which the interconnect delay dominates the transist

Abstract:

An important component of any chemiresistive gas sensor is the way in which the resistance of the sensing film is interrogated. The geometrical structure of an electrode can enhance the performance of a gas-sensing device and in particular the performance of sensing films with large surface areas, such as carbon nanotubes. In this study, we investigated the influence of geometrical structure on the performance of gas sensors, combining the characteristics of carbon nanotubes with a novel gas sensor electrode structure based on fractal geometry. The fabricated sensors were tested with exposure

Abstract:

Frequency-response analysis is critical in circuit design. Frequency response encodes crucial information, like gain, accuracy, bandwidth, response time, phase shift, stability, and more. Unfortunately, existing methods are either algebraic and obscure or approximations with inaccuracies. So applying them to more complex circuits is often arduous or unreliable. This paper proposes recursive shunt-circuit transformations: a simple, rigorous, and insightful analytical method for conceptualizing and designing electronic circuits. The method asserts that (a) each equivalent capacitance shunts away

Abstract:

This paper presents an in situ time-based sensor designed to provide process authentication. The proposed sensor leverages the inherent metal routing within the chip to measure the RC time-constants of interconnects. However, since the routing metal is typically designed to minimize resistance and capacitance, the resulting small RC time-constants pose a challenge for direct measurement. To overcome this challenge, a “three-configuration” measurement approach is introduced, incorporating two auxiliary components—poly resistor and metal-insulator-metal (MIM) capacitor—to generate three amplifie

With the increasing integration density of power control unit (PCU) modules, more functional power converter units are integrated into a single module for applications in electric vehicles or hybrid electric vehicles (EVs/HEVs).

Due to the constraints from the placement of power dies and liquid cooling schemes, heat-flow paths from the junction to coolant are possibly inconsistent for power dies, resulting in different thermal resistance and capacitance (RC) characteristics of power dies.

BaTiO3–(Bi1/2K1/2)TiO3 (abbreviated as BT-BKT) solid solution ceramics, as a lead-free PTC (positive temperature coefficient of resistivity) thermistor material usable over 130°C, has been synthesized by sintering in N2 atmosphere and after annealing in air over 1200°C. In the BT-BKT ceramics with PTC property, the impedance/modulus spectroscopic plots have revealed that a third resistance-capacitance (RC) response besides grains and grain boundaries. Using the remote electron beam induced current (REBIC) configuration, imaging has revealed EBIC contrast consistent with the presence of negativ

Abstract:

The lumped capacitance model, which ignores the existence of wire resistance, has been traditionally used to estimate the charging and discharging power consumption of CMOS circuits. We show that this model is not correct by pointing out that MOSFETs consume only part of the energy supplied by the source. During this study, it was revealed that about 20% of the power is consumed in the wire resistance of the buffered global interconnect, when the interconnect is modeled with RC tree networks. The percentage goes up to 30 when RLC model is used indicating the importance of inductance in interco

Abstract:

The electrical properties of ZnTe–Ti/Al Schottky junctions were investigated by the impedance spectroscopy (IS) method. Current-voltage (I-V) and capacitance-voltage (C-V) measurements were also performed. The studied samples were the CdTe quantum dot structures embedded in ZnTe matrix and a reference ZnTe sample without quantum dots. C-V characteristics confirmed the presence of quantum dots (QDs) in the structures. Electric modulus and impedance data were analyzed. IS studies proved that long-range conductivity governs the relaxation processes in the junctions. For both samples, the data wer

The idea of fractural calculus appeared almost at the same time as the development of conventional differential calculus began.

Abstract:

Equivalent circuit modelling (ECM) is a powerful tool to study the dynamic and non-linear characteristics of Li-ion cells and is widely used for the development of the battery management system (BMS) of electric vehicles. The dynamic parameters described by the ECM are used by the BMS to estimate the battery state of charge (SOC), which is crucial for efficient charging/discharging, range calculations, and the overall safe operation of electric vehicles. Typically, the ECM approach represents the dynamic characteristics of the battery in a mathematical form with a limited number of unknown par

The need for compact models for ICs is a well-recognized problem in electronics cooling simulations of systems containing multiple PCBs and many devices per board. The disparate length scales inherent in the problem and the necessity of resolving these size scales render the computational problem intractable. Many resistance-capacitance (RC) network compact models have been proposed in the literature. We present a methodology to automatically construct both the topology and characteristics of the reduced-order or compact models of devices [primarily Integrated Circuit (IC) packages] for use in

The use of dynamic resistance–capacitance (RC) grey-box models to estimate building thermal energy demands is a well-known strategy.

This research introduces a simple methodology that combines parameter identification from white box generated data and simplified theoretical building thermal equations to create functional and reliable RC model variations from an original grey-box model.

Abstract:

Continuing improvement of microprocessor performance historically involves a decrease in the device size. This allows greater device speed, an increase in device packing density, and an increase in the number of functions that can reside on a single chip. However higher packing density requires a much larger increase in the number of interconnects. This has led to an increase in the number of wiring levels and a reduction in the wiring pitch (sum of the metal line width and the spacing between the metal lines) to increase the wiring density. The problem with this approach is that—as device dim
