This session focuses on advances in mm-wave and RF digital transmitter and power amplification (PA) technologies, showcasing innovative designs across various CMOS nodes. The papers enhance system-level performance and integration for modern communication systems. The first paper introduces a mm-wave transmitter using a digital-to-phase converter (DPC) in 28nm CMOS. The second presents a mm-wave digital Cartesian transmitter with impedance-compensated RFDACs in 40nm CMOS. The third explores an RF digital PA with dynamic range pulse modulation in 22nm FD-SOI. The fourth introduces a UWB all-digital transmitter with hybrid FIR filtering in 28nm CMOS. The final paper presents a bits-to-RF digital transmitter with time-interleaved multi-subharmonic-switching DPAs in 65nm CMOS.
