Abstract :
In this paper, we propose a new transmitter architecture of delta-sigma modulator. Highly efficient switched mode power amplifier is applicable with proposed architecture. Reconfigurability in channel selection and reduction of complexity are mainly addressed. The transmitter architecture has been applied to IEEE 802.11n wireless LAN system and validated by MATLAB simulation.
