CONTENTS • Motivation • Structure of ADC • Circuit Design • Measurement • Conclusion
II. StructureofADC • (7bit) High speed ADC main Structure • F/I Structure : Low Power Consumption, Small Chip Area, and High Speed Conversion Rate
III. CircuitDesign ※ The propose design techniques ※ I. F/I structure for low power consumption and small chip area. II. The proposed Self-calibration Circuit.
III. Circuit Design We need a self-calibration for reduce offset error
III. CircuitDesign LSB : 1.7mV It can decide C-DAC resolution for self-calibration
