Self-calibrating continuous-time delta-sigma modulator |
摘要 |
A self-calibrating continuous-time delta-sigma modulator determines whether time constants of its internal integrators are too large or too small by injecting a calibrating sequence into the modulator and examining a correlation between the calibrating sequence and a modulator output sequence. Then the time constants of the internal integrators are adjusted accordingly. In one embodiment, the correlation is exploited based on matching a noise transfer function of the modulator using an adaptive filter based on a least mean square (LMS) algorithm.
