0.37mW/Gb/s low power SLVS transmitter for battery powered applications

A power-efficient voltage-mode transmitter for battery powered mobile applications was designed. The proposed transmitter consists of a power optimized 16:2 serializer, a data-aligner, 2:1 multiplexing pre-driver, and an I/O driver with segment control for impedance matching. With scalable low-voltage signaling (SLVS) with the output swing of 200mVp-p and power optimization for digital blocks, 0.37mW/Gb/s power consumption was achieved. The test chip for 4.8 Gb/s interfaces was designed in a 65nm 1.2V supply CMOS logic process. The proposed I/O specifications are appropriate for MIPI M-PHY systems.
