This paper presents a non-linear dynamic model of a permanent capacitor single-phase induction motor. The D–Q axis model of the permanent capacitor induction motor, based on the state vector analysis of the system is conducted; revealing the periodic and chaotic phenomenon under different system parameters. Accordingly, a chaotic-speed fan can be achieved by appropriately varying the motors’ in...

An error cancellation technique is described for suppressing capacitor mismatch in a successive approximation A/D converter. At the cost of a 50% increase in the conversion time, the first-order capacitor mismatch error is cancelled. Methods for achieving top-plate parasitic insensitive operation are described, and the use of a gain-and offset-compensated opamp is explained. SWIT-CAP simulation...

This study deals with the design of distributed power systems and optimal capacitor placement based on the ANFIS (Adaptive Network Fuzzy Inference Systems) using Mamdani-type fuzzy inference model. Traditionally, this problem of optimal capacitor placement has been solved through various optimization techniques, but it is less accuracy of finding placement and more time consuming. This can be a...

A capacitor-based circuit model is proposed to explain the electrochemical delamination of two-dimensional materials from their native substrates where produced gas bubbles squeeze into the interface. The delamination is actually the electric breakdown of the capacitor formed between the solution and substrate. To facilitate the procedure, the backside of the ubstrate has to be shielded so that...

This paper compares a stub and a decoupling capacitor for power supply noise reduction. A quarter-length stub attached to the power supply line of an LSI chip works as a band-eliminate filter, and suppresses the power supply bounce of the designed frequency. The conditions where the stub is more effective than the same-area decoupling capacitor are clarified. The stub will work more efficiently...

An automated spark test system based on combining field emission and spark measurements, exploiting a discharging capacitor is investigated. In particular, the remaining charge on the capacitor is analytically solved assuming the field emitted current to follow the Fowler Nordheim expression. The latter allows for field emission measurements from pA to A currents, and spark detection by complet...

This paper presents a predictable fixed gain instrumentation amplifier using switched capacitor instead of resistor to improve the accuracy of the gain as 10. This instrumentation amplifier builds up by two operational amplifiers which connect by switched capacitor. These switched capacitors are used to stable the whole circuit, fix the gain of total instrumentation amplifier. Using two operati...

The study of power management techniques has increased drastically within the last few years corresponding to the vast increase in the use of portable, handheld battery applications. These power management systems typically contain several LDO voltage regulators that require large external capacitors. The large external capacitors can not be fully integrated in standard CMOS technologies and hi...

This paper analyzes the advantages and limitations of using the floating(or flying-) capacitor technique as a building block with differential input and either differential or single-ended output to implement voltage amplifiers, multiplexers, and coherent amplitude demodulators. Theoretical analysis, supported by experimental results, shows that the fully differential configuration has a better...

A capacitor is formed when a level-sensing electrode is installed in a vessel. The metal rod of the electrode acts as one plate of the capacitor and the tank wall (or reference electrode in a non-metallic vessel) acts as the other plate. As the level of the material being measured rises, the air or gas normally surrounding the electrode is displaced by the material’s different dielectric consta...
