摘要：
A device that performs Quantization Noise-Shaping and operates at high clock rates. The device can be implemented in parallel with large parallelization factors to produce extremely high throughput. The device has two feed-forward filters that can be implemented using standard parallel Digital Signal Processing techniques. The device can be used in various systems such as Digital-to-Analog Converter (DAC) system and Fractional-N frequency synthesis systems.
