Reconfigurable of current-mode differentiator and integrator based-on current conveyor transconductance amplifiers

The reconfigurable of the differentiator and integrator based on current conveyor transconductance amplifiers (CCTAs) have been presented in this paper. The proposed configurations are provided with two CCTAs and grounded elements. The configurations can be operated in the differentiator and integrator by selecting external passive elements. The input and output currents have low and high impedances, respectively; therefore, the configurations can be cascaded without additional current buffer. The proposed configurations can be electronically tuned by external direct current (DC) bias currents, and it also has slight fluctuation with temperature. An application of universal filter is demonstrated to confirm the ability of the proposed configurations. The results of simulation with Pspice program are accordance with the theoretical analysis.

A User-Centric Case for Rights Reversions and Other Mitigations: The Cultural Capital Project Submission to ISED Consultation on Term Extension

Term extension is unlikely to benefit any but the largest of rightsholders, and indeed, in general independent creators typically do not benefit greatly from the promised financial exploitation promised by copyrights. This has been made even more evident by the COVID pandemic - while copyrighted works are consumed more than ever, independent creators have sunk further into poverty. We propose mitigation strategies for term extension that would help the people who are creating Canada’s cultural landscape, as well as additional actions that would alleviate additional current copyright losses.

Physical nature of 'anomalous' electrons in high-current vacuum diodes

Introduction/purpose: A fundamental theoretical explanation is given for the fact that in subnanosecond vacuum diodes there exists a group of electrons with kinetic energies much higher than the applied voltage (multiplied by the value of the elementary charge) qUmax. Methods: A mathematical method is used based on the numerical solution of the Vlasov-Poisson differential equations system for one-dimensional vacuum diodes of various designs. Results: It is shown in detail that the so-called "anomalous" electrons appear in the transient time domain characterizing the processes of establishing current flow in vacuum diodes. Conclusion: It has been convincingly shown that the presence of "anomalous" electrons is not associated with either the diode design or the presence of additional current carriers. In vacuum diodes with a subnanosecond leading edge of the voltage pulse, the excess of energy over qUmax can be over 20%.

DESIGN FEATURES OF MULTI-BIT CMOS-CNI-ADC TO CREATE MULTI-CHANNEL HIGH-SPEED DSP SYSTEMS WITH INCREASED FAULT TOLERANCE

The features and possibilities of using foreign and domestic foundry technologies in the creation of CMOS-ADC for high-speed multichannel DSP systems with increased fault resistance to the effects of TKCH are considered. The architecture and technique of ADC balancing, which provide an increase in the conversion rate when several ADCS operate in the alternating mode, are presented. The technique of double reservation of sources of «weight» currents is considered. The necessity of using an additional current source and dual series-connected CMOS transistors instead of single transistors of the same conductivity type is substantiated. It is noted that the proposed solutions provide effective amortization of the impact of TKCH with the most "dangerous" energies of 20-100 MeV/nucleon

A Case Study: Response Mechanics of Irregular Rotational Tidal Flows to Outlet Regulation in Yangtze Estuary

Responses of irregular rotational tidal flows to an outlet regulation (the Guyuan Sand (GYS) regulation) in the three-level branching Yangtze Estuary are studied by a high-resolution numerical model and theoretical analysis. The project is launched around GYS at the outlet of the North Branch of the Yangtze Estuary. The tidal flows around GYS are rotational and become irregular under the influences of the runoff-tide interactions, rapidly varying topographies and complex solid boundaries in coastal areas. Three designs of GYS regulation were studied, including various diversion dikes and new outlets of different widths. The regulation disturbs the irregular rotational flows around GYS, and further changes the estuarine tidal processes and the water exchange between different branches of the branching Yangtze Estuary. It was interesting to find that additional current and additional storage are formed along the North Branch when a southward outlet and the clockwise rotational flow met around GYS. This special phenomenon is named “guide effect” in this study. The guide effect, together with common resist effect (arising from the narrowed outlet channel), reshapes the estuarine tidal processes. Based on the simulation result and a theoretical analysis, response mechanics of irregular rotational tidal flows to the outlet regulation in complex branching estuaries are quantitatively studied.

A low quiescent current low dropout voltage regulator with self-compensation

This paper proposed a low quiescent current low-dropout voltage regulator (LDO) with self-compensation loop stability. This LDO is designed for Silicon-on-Chip (SoC) application without off-chip compensation capacitor. Worst case loop stability phenomenon happen when LDO output load current (Iload) is zero. The second pole frequency decreased tremendously towards unity-gain frequency (UGF) and compromise loop stability. To prevent this, additional current is needed to keep the output in low impedance in order to maintain second pole frequency. As Iload slowly increases, the unneeded additional current can be further reduced. This paper presents a circuit which performed self-reduction on this current by sensing the Iload. On top of that, a self-compensation circuit technique is proposed where loop stability is selfattained when Iload reduced below 100μA. In this technique, unity-gain frequency (UGF) will be decreaed and move away from second pole in order to attain loop stability. The decreased of UGF is done by reducing the total gain while maintaining the dominant pole frequency. This technique has also further reduced the total quiescent current and improved the LDO’s efficiency. The proposed LDO exhibits low quiescent current 9.4μA and 17.7μA, at Iload zero and full load 100mA respectively. The supply voltage for this LDO is 1.2V with 200mV drop-out voltage. The design is validated using 0.13μm CMOS process technology.

FACTORS AFFECTING CAPITAL STRUCTURE ON REGIONAL COMPANY OF BKK RURAL BANKS IN SUKOHARJO REGENCY

The analysis result shows that sales positively affect the capital structure, it means that more sales increase is financed by debt. The asset structure does not positively affect the capital structure, it means that additional current assets are more financed from debt.Profitability has no negative effect on capital structure, it means that profits earned by the company can be partially replanted into the company to increase their own capital. Growth does not negatively affect the capital structure, it means a declining growth rate from year to year due to limited own capital, so asset growth is still financed by debt.Based on the F tests, it shows the sales, asset structure, profitability, growth affects the capital structure simultaneously. Coefficient of determination R², Adjusted R Square value is obtained which shows sales, asset structure, profitability, and growth can explain the structure of capital, the remainder is explained by the residual variable or outside of this study. Keywords: sales, asset structure, profitability, growth, and regression linear multiple.

Uncertainties in Current Measurements in the Northern North Sea

A met–ocean measurement program of waves and current profiles at five locations in the northern North Sea was performed over a period of approximately 5 years. Despite quality control, the measured current speed data contained more noise than expected and large discrepancies were observed between overlapping current speed data measured by different current profilers at the same locations and water depths. Some of the noise and discrepancies can be explained by the influence from surface waves. The current measurements from instruments attached to a surface buoy indicated that these suffered from the influence of surface waves. Further investigations of the uncertainties in current speed data were carried out through three phases of a current verification study, where both additional current measurements and data analysis were done. Comparisons of overlapping measured current speed showed large deviations, suggesting that the accuracy of current measurements is not as good as the user expects. These presented results are in contrast to previous studies of overlapping current measurements.
