MICL Seminar

Design Issues for High Performance ADCs

Stacy Ho

This special data conversion lecture will cover the following topics:
1. ADC non-idealities (effects on SNR and THD due to quantization, clock jitter, noise, DNL, INL)
2. Noise (1/f, thermal, analysis and simulation methods, short channel noise)
3. ADC application examples (GSM and Imaging)
4. Driving the ADC input (Signal dependent loading, boosted and boot-strapped switches, kickback, buffers)
5. Comparator Design (Analysis of Metastability, offset)
6. Capacitor Matching (Accuracy requirements, layout techniques, shuffling)
7. Driving the ADC reference

Stacy Ho received the BS and MS degrees in electrical engineering from the Massachusetts Institute of Technology in 1992. From 1992 to 1999, he was with the High Speed Converter group of Analog Devices, Wilmington, MA, working on CMOS analog-to-digital converters for imaging and communications applications. Since 1992, he has been with the Communications Division of Analog Devices, working on RF and baseband circuits for GSM.
