  1. RPS A/D Converters in Data Conversion HSMC m5151117Yumiko Kimezawa

  2. Outline RPS • The measurement of ECG signals • A/D converter component • Future work

  3. The measurement of ECG signals RPS • Difficult due to many kinds of disturbing signals • 50/60 Hz interference • False signals caused by body movement • and so on • ECG potentials • Around 1 mV • can sometimes rise to 300 mV due to disturbing signals • Frequency • 0.1 ~ 300 MHz • Impedance • 1 ~ 20 KΩ

  4. A/D converter component RPS • Device description • 14-bit, 150 MS/s A/D converter • Manufacturing part number • AD9254 • Manufacturer website • www.analog.com

  5. Future work RPS • Continuing to investigate how to operate an A/D converter • Operating the A/D converter • Exercising A/D converter performance test • Collecting data using the SignalTap II Logic Analyzer • Analyzing the data in the numerical analysis software

  6. RPS

  7. Implementation of ADC RPS
