摘要

To address the challenge of extending the transmission range of implantable TXs while also minimizing their size and power consumption, this paper introduces a transcutaneous, high data-rate, fully integrated IR-UWB transmitter that employs a novel co-designed power amplifier (PA) and antenna interface for enhanced performance. With the co-designed interface, we achieved the smallest footprint of 49.8mm2 and the longest transmission range of 1.5m compared to the state-of-the-art IR-UWB TXs.
