Low-voltage, Low-power Solutions For Wireless Autonomous Sensors Aimed For Ami Applications

This paper deals with the RF communication issues of low-voltage, low-power autonomous sensors. The sensors gather all or part of the energy needed for their operation from the environment, thus challenging the design engineers to find ultra low-power solutions. A major part of the power consumption of autonomous sensors is drawn by the communication circuitry, thus it is of great importance to find the optimal modulation scheme and structures. Three analog multipliers were investigated from the aspect of consumption and an alternative communication method is also presented
