摘要：
A 65nm digitally-modulated polar transmitter incorporates a fully-integrated 2.4GHz efficient switching Inverse Class D power amplifier. Low power digital filtering on the amplitude path helps remove spectral images for coexistence. The transmitter integrates the complete LO distribution network and digital drivers. Operating from a 1-V supply, the PA has 21.8dBm peak output power with 44% efficiency. Simple static predistortion helps the transmitter meet EVM and mask requirements of 802.11g 54Mbps WLAN standard with 18% average efficiency.
