摘要:
A hybrid delta sigma ADC architecture and method is disclosed to implement a high-resolution delta-sigma modulator with a single-bit output. The system contains a low-order multi-bit analog noise-shaping loop, followed by a high-order single-bit digital modulator. The combination simplifies the analog modulator, and allows the use of most of the full-scale input range.
