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.
