Device and method for digitizing a receiver signal strength indicator (RSSI) signal |
摘要 |
A device and method for digitizing a RSSI signal in a wireless transmission system is disclosed, which comprises a micro-controller having a ring counter and a controller, a low-pass filter, and a comparator. To start a digitization process, the controller gradually increases a numeric control signal to control a ring counter to generate a square wave with different duty cycle. Subsequently, the square wave is filtered by a low-pass filter to obtain a DC threshold voltage. If the threshold voltage is larger than the RSSI voltage, the digitization process is complete and the final numeric control signal represents the digitized RSSI signal.
