A WIRELESS DIGITAL COMMUNICATION DEVICE, AND A PEAK-DETECTOR |
摘要 |
A peak detector that is particularly suitable for measuring the peak value of an RSSI-signal in a digital communication device. The peak detector includes a peak value storage capacitor which is charged by a high current or by a low current. When the RSSI-signal is greater than the output voltage of the peak detector, the storage capacitor is charged with the low current. When the RSSI-signal is substantially greater than the output voltage of the peak detector, the storage capacitor is charged with the high current. Herewith, it is achieved that the peak value of the RSSI-signal is determined quickly, without any overshoot, i.e. the peak value is determined accurately. |
