| titleOfInvention | Pipeline successive approximation analog-to-digital conversion circuit |
| abstract | The invention provides a pipeline successive approximation analog-to-digital conversion circuit, and belongs to the field of integrated circuit design. Comprising three pipeline stage circuits and an adder. The DAC capacitor array of the three pipeline-level circuit adopting the capacitor switch control time sequence based on the common-mode level in the conversion stage is only half of the traditional capacitor array, because the quiescent current consumed by the margin amplifier is in direct proportion to the square of the load capacitor, and the pipeline successive approximation analog-to-digital converter adopts the SAR ADC based on the capacitor switch control time sequence of the common-mode level, when the circuit state changes, the capacitor in the DAC capacitor array is at V ref And V cm Or V cm And GND, unlike conventional switch control timing, the DAC capacitor array is switched at V ref And GND. Therefore, the pipeline successive approximation analog-to-digital converter provided by the invention greatly reduces the power consumption. |
