Course Content: |
- The functions and applications of D/A and A/D converters.
- Ideal DACs and ADCs: operation, specifications, metrics.
- Converter nonidealities: offset and gain error, DNL, INL, non-monotonicity, missing codes, SNR, DR, SFDR, etc.
- DAC architectures: decoder-type, binary, thermometer, hybrid DACs.
- DAC circuit structures: R-string and R-ladder circuits, current-steering, charge- redistribution, hybrid, segmented DACs.
- ADC architectures: integrating, successive-approximation and algorithmic, pipelined, time-interleaved, sub ranging and two-step, interpolating, folding and flash ADCs.
- ADC circuits: resistor-string, charge-redistribution, current-steering, hybrid, folding/interpolating circuits.
- Operational principles of delta-sigma (D-S) DACs and ADCs.
- Main architectures for the realization of D-S DACs and ADCs.
- Circuit realization and nonidealities of D-S data converters.
Planned schedule of discussions:
- Review of data converter operation and characterization (1/2 week)
- DAC architectures, structures, nonidealities (1 week)
- ADC architectures, structures, nonidealities (2 weeks)
- Oversampling data converters (6 weeks)
