Digital technique for excess loop delay compensation in a continuous-time delta sigma modulator |
| 摘要 |
A continuous time delta sigma modulator includes a quantizer and a reference module. The quantizer includes: a first comparator that generates a first digital output based on a comparison of a first reference potential with an input generated based on a sample of an analog signal; and a second comparator that generates a second digital output based on a comparison of a second reference potential with the input generated based on the sample of the analog signal. The reference module varies the first and second reference potentials based on the first and second digital outputs. |
