Original Kurzfassung:
In this paper, an ultra-low-power impulse-radio
ultra-wide-band transmitter (IR-UWB) is presented, enabling
various wireless bio-sensor applications. To design and implement
this circuit, open-source IC design tools were utilized, which,
lacked a module for inductor generation. Firstly, a flow for
inductor generation was developed and then evaluated. Secondly,
an inductor and balun were created with the flow and then used
in the circuit implementation. The presented circuit includes
an integrated oscillator, power amplifier, matching network,
and delay stage. The layout area occupies 0.214mm2 in opensource
SKY130 technology. The total power consumption and
energy-per-bit of the presented transmitter were calculated for
5.12 kbps with a simple 2-pulse-per-bit modulation scheme and
are 0.877?W and 171.28 pJ, respectively. The power spectrum
density of the output is in compliance with the IEEE 802.15.41-
LRP-UWB-PHY standard, US FCC, and European ETSI limits,
enabling a wide usability of the circuit.
