Abstract :
This work presents an element selection logic (ESL) for a radio frequency digital to analog converter (RF-DAC) based multistandard transmitter in 65 nm CMOS. After introducing the transmitter system and the basics of mismatch shaping, the ESL is applied to an OFDM transmitter. The design is optimized with respect to the signal properties and synthesis is done for the mentioned CMOS technology. Simulation results show a significant improvement of the signal quality in the desired band.
