This paper explains about the voltage output for DC to DC boost converter between open loop, PID controller and fuzzy logic controller through Matlab Simulink. Simulink input voltage was set at 12V and the voltage reference was set at 24V. The analysis on the deviation of voltage resulted that the difference between reference voltage setting and the output voltage is always lower. Comparison be...

Conventional CMOS charge pump circuits have some current mismatching characteristics. The current mismatch of the charge pump in the PLLs generates a phase offset, which increases spurs in the PLL output signals. In particular, it reduces the locking range in wide range PLLs with a dual loop scheme. A new charge pump circuit with perfect current matching characteristics is proposed. By using an...

The square cells specified by Ruby language, called Ruby cells, can be relocated by either rotation, horizontal flip, vertical flip or shifting in a regular array structure such as FPGA (Field Programmable Gate Array) or Cell Matrix . In this paper, the behaviours of those relocations have shown at two different levels, called architectural level and logic level. In other words, the behavioural...

This paper presents a design of a high performance and low power consumption triple-track magnetic sensor chip which was fabricated in TSMC 0.35 μm CMOS process. This chip is able to simultaneously sense, decode and read out the information stored in triple-track magnetic cards. A reference voltage generating circuit, a low-cost filter circuit, a power-on reset circuit, an RC oscillator, and a ...

Unipolar potential measurements are carried out on a circular homogeneous conducting lamina. One set of potential measurements is made using an averaging net work for the zero potential reference. A second set of potential measurements is made with reference to the Frank-Kay "zero" potential reference on the outside ground of the dipole generating circuit. Both sets of unipolar potential measur...

A low voltage, micro-power, curvature-corrected bandgap reference is presented that is capable of working down to input voltages of 1.1 V in a relatively inexpensive process, MOSIS 2 μm technology. This is a vanilla N-well CMOS process technology with an added P-base layer. Second order curvature correction for this reference is accomplished by a versatile piecewise-linear currentmode technique...

A high precision temperature insensitive current and voltage reference generator is presented. It is specifically developed for temperature compensated oscillator. The circuit, designed using MXIC 0.5um CMOS technology, has an operating voltage that ranges from 2.6V to 5V and generates a voltage of 1.21V and a current of 6.38 A. It exhibits a variation of ±0.3nA for the current reference and a ...

Improving efficiency of electrical machine is of paramount importance to optimization of operational and resource management. Efficiency method which do not account for iron loss could undermine the effective efficiency estimation. This paper simulates the efficiency variations of electric machine in both transient and steady state, magnetic flux linkages are used instead of the traditional cur...

This paper develops a Lyapunov approach to control design for grid connected inverter. The control objective is to track a reference current which is proportional to the fundamental harmonic of the grid voltage. By using the internal model principle, the grid voltage and the reference current are described as the outputs of an autonomous linear oscillatory system. The state of this oscillatory ...
