A Fractional-N Frequency Synthesizer with a Sigma-Delta Modulator for Polar Transmitter
碩士 === 國立臺灣大學 === 電信工程學研究所 === 92 === In 2.5G or 3G communication system, the envelope of the modulation signal is non-constant, so it is a trade-off between the linearity and the efficiency of a power amplifier in the transmitter. Polar transmission techniques offer the capability of multi-standard...
