Abstract :
A digital-RF transmitter based on direct up-conversion with segmented cell structure is presented. The prototype is designed in 90-nm CMOS process. The implemented transmitter achieves an ACLR1 / ACLR2 of -37.89 dBc / -46.33 dBc for WCDMA and -37.19 dBc / -44.11 dBc for LTE with 5 MHz channel bandwidth.
