Energy-efficient Sensor Circuit Design for Space Applications

This paper presents energy-efficient, safety-critical wireless sensor circuits for next-generation space satellites and space robots. The hardware design and implementation proposed here exploits a novel control algorithm and ensures that appropriate reconstructed sensing qualities can be achieved. In this paper we demonstrate that focus on preserving the clarity of important power consumption features, such as dynamic power dissipation, at peak voltage ratios of 120 W. With this approach, features in the circuit that may be important for recognition are well preserved, even at high energy dissipation -a maximum power rate of about 125 W can be sustained.
