SECTION 5.1: TESTING DACs

A Deterministic Dynamic Element Matching Approach for Testing High Resolution ADCs Using Low Accuracy DACs (Design Number: 68091)

Testing of high-speed DACs using PRBS generation with "Alternate-Bit-Tapping"

Testing of high-speed Digital-to-Analog Converters (DACs) is a challenging task, as it requires large number of high-speed synchronized input signals with specific test patterns. To overcome this problem, we propose use of PRBS signals with an “Alternate-Bit-Tapping” technique and eye-diagram measurement as a solution to efficiently generate the testvectors and test the DACs. This approach cove...

In situ Probe Microphone Measurement for Testing the Direct Acoustical Cochlear Stimulator

Hypothesis: Acoustical measurements can be used for functional control of a direct acoustic cochlear stimulator (DACS). Background: The DACS is a recently released active hearing implant that works on the principle of a conventional piston prosthesis driven by the rod of an electromagnetic actuator. An inherent part of the DACS actuator is a thin titanium diaphragm that allows for movement of t...

SECTION 4 DACs FOR DSP APPLICATIONS

SECTION 8 ADCs FOR SIGNAL CONDITIONING

The trend in ADCs and DACs is toward higher speeds and higher resolutions at reduced power levels. Modern data converters generally operate on ±5V (dual supply) or +5V (single supply). In fact, many new converters operate on a single +3V supply. This trend has created a number of design and applications problems which were much less important in earlier data converters, where ±15V supplies and ...
