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 :
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.
This technology is protected by several patents applications families
The maturation project aims at the realization and qualification of a demonstrator in CMOS 65nm
