title = "A SDR Transmitter Baseband-to-IF IC with Digital Out-phasing Exponential Modulation in a 65nm CMOS LPE",
abstract = "A digital pulsed modulation for high efficiency and linearity, switched-mode power amplifier (PA) is proposed. Based on a new representation of digital modulated signals at IF called Out-phasing Digital Exponential Modulation (ODEM), the paper presents the concept, simulations and measurements of an integrated solution in CMOS (baseband and IF) and GaN (PA) technologies. It exhibits a faster decaying spectrum, when compared to Out-phasing pulse-width modulation (OPWM), and a power spectrum that fulfills the spectral emission mask for 64QAM LTE standards. The implementation in a 65 nm CMOS LPE process from GF based on the baseband solution, shows that the SEM requirements for LTE standards are fulfilled. The circuit implementation of the baseband IC is presented is based on digital CMOS circuits.",
