  • Dual-mode delta-sigma analog to digital converter system and method
    Patent number: 7164376
    Abstract: A dual-mode delta-sigma analog to digital converter system is disclosed that uses a feed forward modulator and includes a low frequency resonator circuit and a high frequency resonator circuit and includes a feed-forward path from the final integrator in the high-frequency resonator circuit to a summer. The digital converter system includes a selection unit for permitting the high frequency resonator circuit and the low frequency resonator circuit to be employed in a first mode of operation. The system also permits the high frequency resonator circuit and the feed-forward path from the final integrator in the high-frequency resonator circuit to the summer to be disabled in a second mode of operation.
    Type: Grant
