Tunable bandpass sigma-delta digital receiver |
摘要 |
A tunable bandpass sigma-delta modulator analog-to-digital converter (A/D converter or ADC) utilized in conjunction with a digital signal processor (DSP) to eliminate the analog frequency synthesizer in a radio design is disclosed. The sigma-delta ADC greatly reduces the analog circuitry requirements and ensures that the circuitry is suitable for very large scale integration (VLSI). The all-digital DSP ensures the highest level of VLSI and provides for high performance frequency synthesis and translation completely in the digital domain.
