Low-power RFIC Design


We have extensive experience of working with low power circuits for consumer applications. Our experience has been gained in cooperation with world leading companies in different segments where we have teamed up to design and produce production worthy designs.

Applications


Below is a list of the standards that we have designed for. Our involvement has been everything from specification development to characterized circuit in volume production.
  • GSM/EDGE
  • WCDMA
  • Bluetooth
  • WLAN (802.11a/b/g/n)
  • GPS
  • DVB-H/T, DMB
  • UWB
  • Cordless
Expertise
For the successful completion of complex projects it is of paramount importance to have experience of the individual tasks and problem areas involved.

Our experience includes among other things the following:
  • Radio system specification
  • Receiver and transmitter architectures up to 10GHz including all relevant building blocks like LNAs, mixers, filters, VGAs/AGCs etc.
  • Synthesizer designs, fractional and integer N, including VCOs and fully integrated PLLs including loop filters
  • Digital control functions and calibration circuitry
  • Multi-function radio designs
  • Device and package modeling
  • Cross-talk modeling and simulations
  • Validation and interoperability test of multi-function radios in an in-house and well-equipped lab
Technologies
The designs have been produced in several different technologies from several foundries. The most common however are RFCMOS 90-45nm and BiCMOS 0.35um-0.18um.
