Abstract:
SAR-ADCs are very popular and suitable for conversions up to few tens of MHz with 8 to 12 bits of resolution. A very popular type is the Charge Redistribution SAR-ADC which is based on a capacitive array. Higher speeds can be achieved by using the interleaving technique where a number of SAR-ADCs are working in parallel. These speeds, however, can only be achieved if the reference voltage can cope with the switching of the capacitive array. In this thesis the design of a programmable voltage reference generator for a Charge Redistribution SAR-ADC was studied. A number of architectures were stu

Given a high enough electric field across the cell membrane, the electroporation process can become irreversible, leading to cell destruction.

The growth of embedded generation and portable electrical installations has led to an increased demand for low cost, flexible and reliable generator systems for military and commercial applications. An interior permanent magnet (IPM) machine has high power density due to its reluctance torque and magnetic torque components so it can produce a large constant power-speed range. However, an IPM machine needs demagnetizing current at high-speed during the flux-weakening region and thus develops an inverter shutdown problem in an uncontrolled generator mode operation. In order to overcome the disad

碩士<br>國立臺北大學<br>電機工程學系<br>105<br>This paper proposes a new design of current source, which is All-MOS transistor designed without bipolar transistor and resistance component. Therefore, the current source has no negative effects of extra process variation and more mask cost.Considering various processes, voltages (1.4V to 1.98V) and temperature (-400C to 1200C), in these extreme conditions the error variation of current is much lower than 1%; therefore, the current source has a low sensitivity of process, voltage, temperature variation.In traditional application, the high frequency oscillator

The propeller lifting line theory will be applied to design the turbine blade at 3.2 m/s current speed. The power generated by different diameters of turbine blade and its corresponding optimal revolutions will be calculated. The efficiency of three blades turbine is higher than that of two blades turbine. A three blades turbine with 0.8 m diameter can reach 3 kW.

In this thesis first the behavior of induction generators under unbalanced voltage conditions is studied. In this context, first the existing schemes for characterizing the unbalance in simple ways have been studied. The two schemes IEC, NEMA which are in use to quantify the unbalance, as an unbalance factor require the use of complex algebra. A new scheme to characterize voltage unbalance, without using any complex algebra has been proposed and its effectiveness is compared with the NEMA scheme.

This paper is to modify some circuit based on product specification in order to make balance of cost and specification. We start to study how to use the least cost to reduce Locking time and increase locking speed of phase lock loops without modifiying original circuit characteristics. In addition, VCO circuit in the system is a high pass filter. Noise of VCO will make contribution to output frequency. So, we must use technique of designi
