RF Signal Generator for 5G Applications
Internet des objets
Infrastructures de 5ème génération
Innovative TX Signal Generation Solution that convert a digital signal to an analog waveform compliant to 3GPP Standards.
This disruptive system promising performances as for the realization of a 5G handset transmitter with moderate hardware complexity and low power consumption.
Architecture intended to address future wireless transmission requirements :
- Sub-6 Ghz 5G,
- Internet Of Things.
The signal generation is based on a piecewise linear approximation, resulting from the use of a differential digital coding associated with a custom digital-to-analog converter (DAC), named here the Riemann Pump. The intrinsic performances of this architecture in terms of quantization noise make the Riemann Pump an efficient DAC for multi-carrier applications.
- Energy efficient data conversion,
- High flexibility radio design and bandwith 3GPP standards compliance,
- Carrier aggregation intrinsic compatibility,
- Low footprint,
- Lab proof-tested solution with fab tapped chips.
The maturation project aims at the realization and qualification of a demonstrator in CMOS 65nm
Integration: from Material to Systems (IMS, UMR 5218)
