摘要：
A novel transmitter architecture is proposed for wireless local area networks (WLAN) and 3(rd) generation (3G) mobile applications. The transmitter is based on the envelope elimination and restoration (EER) architecture applied with two-point delta-sigma modulator (TPDSM). It can integrate digital modulators and power amplifiers without mixers effectively. In addition, the power amplifier can deal with non-constant envelope modulations like QPSK highly efficiently.
