RECEIVER HAVING INTEGRATED MIXER AND SIGMA-DELTA ANALOG-TO-DIGITAL CONVERSION |
| 摘要 |
A receiver with an integrated mixer/Sigma-Delta Modulator configuration for digitizing a relatively low-bandwidth signal modulated on a high-frequency carrier, for example in a radio receiver. The Sigma-Delta Modulator has a continuous-time loop filter (F1, F2) with anti-aliasing characteristics which eliminate the need for a separate lowpass filter between the mixer (MX) and the Sigma-Delta Modulator.
