Abstract:
1. A method of operating a mobile telecommunication device including a power amplifier, a digital baseband processing unit (DBB) including a controller, and an analog baseband processing unit (ABB) including a ramp generator, the method comprising: receiving current ramping sample data having a first bit number in the DBB; reading previous ramping sample data; using the controller to extract a sample difference value between the current ramping sample data and the previous ramping sample data; converting the sample difference value into sample difference ramping data having a second bit number less than the first bit number; transmitting the sample difference ramping data from the DBB to the ABB via a serial interface; generating a ramping up/down signal having the first bit number using the ramp generator in response to the sample difference ramping data; and controlling a power amplifier in response to the ramping up/down signal.
