Method and apparatus for compensating offset drift with temperature |
| 摘要 |
The disclosure provides an analog to digital converter (ADC). The ADC includes a comparator that receives a threshold voltage. A set of elementary capacitors is coupled to the comparator, and receives one of an input voltage and a set of reference voltages. A set of M offset capacitors is coupled to the comparator, and receives one of a primary voltage and a secondary voltage, M is an integer. A difference in the primary voltage and the secondary voltage varies linearly with temperature. |

1. An analog to digital converter (ADC) comprising:
a comparator configured to receive a threshold voltage; a set of elementary capacitors coupled to the comparator, and configured to receive one of an input voltage and a set of reference voltages; and a set of M offset capacitors coupled to the comparator, and configured to receive one of a primary voltage and a secondary voltage, M is an integer, wherein a difference in the primary voltage and the secondary voltage varies linearly with temperature. |
