A 1.04uW Wireless Integrated MEMS Interface in UMC 0.18um CMOS
Résumé
This paper presents an ultra low-power integrated interface for capacitive and resistive MEMS and sensors, intended for use in biomedical applications. The interface encodes the sensed data in the time between transmitted UWB pulses: this reduces the number of transmitted bits and benefits the power consumption. The interface was designed and fabricated in the UMC 0.18m CMOS process: the power consumption of the system was measured to be 1.04W at a sample rate of 37Hz.
