A Remotely Powered Implantable IC for Recording Mouse Local Temperature with +/- 0.09 degrees C Accuracy

Catherine Dehollain

Multiple techniques are presented to implement an ultra-low-power remotely powered implantable system. The temperature is monitored locally by a thermistor-type sensor. The resistive response of the sensor is amplified and resolved in the time-domain. The ...

On the Exploitation of the Inherent Error Resilience of Wireless Systems under Unreliable Silicon

Andreas Peter Burg, Georgios Karakonstantis

In this paper, we investigate the impact of circuit misbehavior due to parametric variations and voltage scaling on the performance of wireless communication systems. Our study reveals the inherent error resilience of such systems and argues that sufficien ...
