VARIABLE TIME ANTI-ALIASING FILTER |
| 摘要 |
A processing system for a capacitive sensing input device comprises a charge integrator, a circuit element having a first resistance, and a first switch coupled with the circuit element. The first circuit element is disposed in series with an input of the charge integrator. The first switch is configured to alter the first resistance to a second resistance when selectively closed during at least a portion of an integration phase of the charge integrator. The second resistance is lower than the first resistance. |
