Abstract |
| A VLF architecture with internal calibration is proposed. The calibration improves the conversion accuracy by reducing the nonlinearity and the conversion scale error, as well as minimizing the zero offset. An important feature of the proposed calibration is that it is implemented with analog blocks used during normal converter operation. The proposed architecture was verified in silicon and measurements show a typical conversion nonlinearity of 30 ppm and a zero offset of less than 0.1 Hz at a conversion ratio of 200 kHz/V. |
