This thesis treats broad aspects of voltage-to-digital converter design. Particular emphasis is placed on material related to designing a converter to satisfy a set of converter specifications that is given in the introduction of the thesis. The converter design is first considered in terms of basic conversion techniques. One technique, known as"successive approximation,” seems best to satisfy the requirements of the design specifications. The “successive-approximation" voltage-to-digital converter requires that its input voltage be compared to a voltage that is systematically generated within the converter. The voltage generated within the converter is derived from digital information. When the internal voltage equals the external applied voltage, a conversion is accomplished and the converter can output its digital information as the numerical equivalent of its input voltage. A major part of the thesis is concerned with basic approaches that might be used in generating a voltage from digital information in a manner that is fast, accurate, stable, and compatible with a fast, accurate, stable comparison operation. Another major part of the thesis presents analysis of specific circuits that are used in the construction of a converter designed to satisfy the introduction’s specifications. A report on the performance of a converter built with the just mentioned circuits is included. / Master of Science

Stress sensitivity of a 16 - bit D/A converter in a molded plastic DIP has been studied. Device performance was shown to change as a function of package stress. The effects of die position in the package and the presence or absence of die coat on package stress and device performance were determined. Finite element methods were employed for system analysis. Device stress sensitivity was attributed to diffused bit transistors and the mechanism assigned to nonuniformity of stress on the device bit transistors. Die coat (silicone gel) was shown to reduce normal and shear stresses and have little or no effect on X-axial stresses. Lowering the die in the package was shown to increase the X-axial stress uniformity from the die center to edge for die-coated parts and alter the value of shear stresses near the die edge for parts without die coat.

The purpose of this research is to determine the linearity and monotonicity of the THS5651IDW digital to analog converter (DAC), a prototype of the future Texas Instruments TLV5651, 10-bit, 125 MHz communication DAC. Testing was conducted at the Texas Instruments facility on Forest Lane, Dallas, Texas. Texas Instruments provided test equipment, software and laboratory space to obtain test data. Analysis of the data found the DAC to be monotonic since the magnitude of the differential nonlinearity (DNL) was less than ± 1 least significant bit (LSB) and the integral nonlinearity (INL) was less than ± 0.5 LSB. The study also showed that the DAC has primarily negative DNL although the DNL is well within the desired specification.
