A novel low-power low-complexity chip solution for tunable UWB transmitter in CMOS 0.18µm technology

In this paper, a novel UWB transmitter chip is proposed, based on the 0.18 μm CMOS technology. A novel transmitting solution is adopted to realize a low-power and low-complexity physical implementation for future high data rate wireless component interconnect and implantable electronic applications. A UWB PA with standby, a digital ring on-off VCO, a subtractor for eliminating base-band component from the output of the VCO, and a narrow pulse generator are employed to achieve the chip with the maximum data-rate of 200Mbps, tunable-band of licensed 3~7GHz, low-power of 8pJ/bit, and a small circuit area of 0.2mm², of which the proposed subtractor, VCO, and PA play the important roles in reducing power dissipation. The simulation results verify that the proposed design is suitable for future potential applications.
