Cartesian Feedback with Digital Enhancement for CMOS RF Transmitter

Abstract : The trend of communication systems with higher data rates requirescomplex modulation techniques. To satisfy the stringent linearityrequirements of the emitter, linearization techniques have attractedmuch attention. Many methods are proposed to reduce the effects ofnonlinearities. We implemented an analog and digital Cartesian feedbacktechnique in an integrated transmitter in 65-nm CMOStechnology. This approach offers flexibility and paves the way formulti-standard linearized RF transmitters.
