Analog to digital converter |
| 摘要 |
An analog to digital converter includes an analog input and a voltage comparator coupled to the analog input for comparing a voltage at the analog input to a digitally synthesized waveform. A digital to analog converter (DAC) generates the digitally synthesized waveform. The DAC includes a plurality of capacitors selectively connected in parallel wherein the period between the selection of capacitors is less than the settling time of the voltage across the capacitors. |

1. An analog to digital converter comprising:
an analog input; a voltage comparator coupled to the analog input for comparing a voltage at the analog input to a digitally synthesized waveform; a digital to analog converter (DAC) for generating the digitally synthesized waveform, the DAC includes a plurality of capacitors selectively connected in parallel wherein the period between the selection of capacitors is less than the settling time of the voltage across the capacitors; wherein the period of the selection is approximately twice the settling time of the voltage across the capacitors. |
