A 100-M/s 2.6-pJ/pulse compact UWB impulse transmitter based on antenna-and-pulse-generator codesign

Abstract

This work presents a novel concept of antenna-and-pulsegenerator codesign for realizing FCC-regulation-compliant IR-UWB transmitters. The method contributes to a compact design that significantly reduces the overall device footprint and energy consumption. A Gaussian mono-pulse generator and a folded-dipole antenna with a bandwidth of 7.8-9.5 GHz are co-optimized, eliminating any matching sections. The energy consumption for each impulse emission is only 2.6 pJ and 100 Mpulse/s operation of the transmitter complies with the FCC mask. The transmitter of this kind shows promise for size-restricted and ultra-low power applications such as medical implants. key words: UWB, impulse radio, ultra-low-power telemetry, medical implant Classification: Microwave and millimeter wave devices, circuits, and hardware

Sub-Milliwatt Transceiver IC for Transcutaneous Communication of an Intracortical Visual Prosthesis

“…In [45][46][47], a much lower data rate of <30 Mbps was reported, which is not well-suited for our data rate requirements for the uplink. In [48], a higher data rate is shown at slightly lower power consumption, but the higher frequency band of 6.8-9 GHz reportedly used will face about 10 dB more attenuation through the skin tissue.…”
