Very Low power wireless design

Power has become a limiting factor in many applications. Specially in portable products, wireless applications and temperature limited products and systems. Therefore it is useful to investigate and develop really low power, "ultra" low power devices ( Integrated circuits and modules) that can be used to build more complex systems. techniques such as low voltage devices, sub-threshold CMOS circuits, energy harvesting etc. all play a part in the design of such devices. A number of low power designs can be done now with state of the art technology, specially for wireless ( RF amplifiers, mixers,detectors, LC oscillators, etc) that were not possible even a few years ago.It is a fascinating area of design effort. Over the past few years the techteam at Signal Processing Group Inc, has been involved in the design of low power circuits for use in RFID, 1.2V battery powered systems and short range wireless sensor based "data tubes". Some of this work is available for discussion. For details or for help in the design of these type of devices please contact SPG at http://www.signalpro.biz.
