Abstract:

<p> Digital imaging is growing rapidly making Complimentary Metal-Oxide-Semi conductor (CMOS) image sensor-based cameras indispensable in many modern life devices like cell phones, surveillance devices, personal computers, and tablets. For various purposes wireless portable image systems are widely deployed in many indoor and outdoor places such as hospitals, urban areas, streets, highways, forests, mountains, and towers. However, the increased demand on high-resolution image sensors and improved processing features is expected to increase the power consumption of the CMOS sensor-based camera

Abstract:

A new concept of current sensor reduction technique called multi-branch current sensing technique (MCST) is proposed in this dissertation. In the proposed current sensing method, one more branch currents are simultaneously measured several times in a single switching cycle by using a single current sensor. After that, the current reconstruction algorithm is applied to obtain all phase currents information. Compared to traditional single current sensor techniques (SCSTs), the proposed method samples the output of the current sensor regularly, and the current sensing dead-zone is dramatically re

Abstract:

The viability of low cost, distributed, and autonomous wireless sensor networks is determined by the affordability of the integration and operation of each sensor node. Self-sufficient nodes which harvest energy from the local environment decrease operating and maintenance costs over extended periods of time. This affordability can be achieved by increasing the power usage efficiency of designs implemented in an older and cheaper CMOS process. This circumvents the use of a more compact technology node which trades increased efficiency for cost. The efficiency of power conversion is determined

Abstract:

A low-energy current-mode algorithmic pipelined ADC targeted for use in distributed sensor networks is presented. The individual nodes combine sensing, computation and communications into an extremely small volume. The nodes operate with very low duty cycle due to limited energy. Ideally these sensor networks will be massive in size and dense in order to promote redundancy. In addition the networks will be collectively intelligent and adaptive. To achieve these goals, distributed sensor networks will require very small,inexpensive nodes that run for long periods of time on very little energy.

Abstract:

Quiescent current leakage test of the VDD supply (IDDQ Test) has been proven an effective way to screen out defective chips in manufacturing of Integrated Circuits (IC). As technology advances, the traditional IDDQ test is facing more and more challenges. In this research, a practical built-in current sensor (BICS) is proposed and the design is verified by three generations of test chips. The BICS detects the signal by sensing the voltage drop on supply lines of the circuit under test (CUT). Then the sensor performs analog-to-digital conversion of the input signal using a stochastic process wi

Abstract:

碩士<br>國立臺灣科技大學<br>電子工程系<br>95<br>A current-mode CMOS DC–DC converter with integrated power switches and on-chip current sensor for feedback control is presented in this paper. The sensed inductor current, combined with the internal ramp signal, can be used for current-mode DC–DC converter feedback control. In addition, no external components and no extra I/O pins are required for the current-mode controller. The DC–DC converter has been fabricated with the TSMC CMOS digital process. The simulation results show that this converter with on-chip current sensor can operate in 1.5 MHz with supply

Abstract:

碩士<br>國立成功大學<br>電機工程學系碩博士班<br>101<br>Due to the growth of consumer electronics market, there are more and more studies in energy saving to prolong service life of electronic products. Because the output voltage of batteries decreases with time (e.g., Li-ion: 2.7–4.2 V), it may be higher or lower than the required supply voltage (e.g., 3.3V). To use the entire battery output voltage range, a non-inverting buck-boost dc-dc converter is a good choice. In this work, an average-current-mode non-inverting buck-boost dc-dc converter with the advantages of high power efficiency, faster transient respo

碩士<br>國立高雄應用科技大學<br>機械與精密工程研究所<br>102<br>Fluxgate is a magnetic sensor which is very sensitive to external magnetic field.This paper demonstrates a ring wire-wound fluxgate with double magnetic cores that can detect the current magnitude by sensing its field.The Metglas2714A magnetic core was stuck to a PMMA ring with the copper wire excitation coil and pick-up coil wound around it.This fluxgate current sensor is able to detect the changes of magnetic flux between saturation and unsaturation of the magnetic core. In this paper, we measure the responses of fluxgate current sensors at various ex

Abstract:

碩士<br>國立交通大學<br>電機工程學系<br>106<br>This thesis presents an architecture of an on-chip current sensor. It is implemented in a LED driver. This sensor has been designed using SenseFET to detect the output current for the feedback control. As a resoult, the output current can be stabilized and the efficiency can be maximized. This chip will be fabricated in TSMC 0.25 1P3M HV CMOS process. The frequency of the system clock is 1.1MHz. The maximum efficiency of the converter is 96.6%. The current error is ±1.7%. The chip area is1535×1269〖um〗^2.
