Design for MOSIS Educational Program (Research) A Deterministic Dynamic Element Matching Approach for Testing High Resolution ADCs Using Low Accuracy DACs

A deterministic dynamic element matching approach to ADC testing

A deterministic dynamic element matching (DEM) approach to ADC testing is introduced and compared with a common random DEM method. With both approaches, a highly non-ideal DAC is used to generate an excitation for a DUT that has linearity that far exceeds that of the test stimulus. Simulation results show that both methods can be used for testing of ADCs but with a substantial reduction in the ...

A Fully Integrated Approach for Better Determination of Fracture Parameters Using Streamline Simulation; A gas condensate reservoir case study in Iran

      Many large oil and gas fields in the most productive world regions happen to be fractured. The exploration and development of these reservoirs is a true challenge for many operators. These difficulties are due to uncertainties in geological fracture properties such as aperture, length, connectivity and intensity distribution. To successfully address these challenges, it is paramount to im...

On the Static Accuracy of Digitally Corrected Analog-to-Digital and Digital-to-Analog Converters

Some basic observations are made about the static accuracy of ADCs and DACs with full digital correction. First, the accuracy of flash ADCs is considered. It is pointed out that the loss in effective resolution due to component mismatch is only about 1 bit, independently of the mismatch level (unless the mismatch is very small). Second, the accuracy of current steering DACs is considered. It is...

Aspects of data acquisition system design

Analog-to-digital converters (ADCs) and digital-toanalog converters (DACs) play an important role in the design of data acquisition systems. ADCs are used to convert analog signals like the output from a temperature transducer, a radio receiver or a video camera into digital signals for processing. Conversely, DACs are used to convert digital signals back to analog signals. For example, the DAC...
