Scaling of process technologies has made power management a significant concern for circuit designers. Moreover, denser integration and shrinking geometries also have a negative impact on circuit reliability. Therefore, fault tolerance is becoming a more challenging problem. Static Random Access Memories (SRAMs) play a significant role in circuit power consumption and reliability of digital cir...

Power Conditioning and Stimulation for Wireless Neural Interface ICs by William James Biederman III Doctor of Philosophy in Engineering Electrical Engineering and Computer Sciences University of California, Berkeley Professor Jan M. Rabaey, Chair Brain machine interfaces have the potential to revolutionize our understanding of the brain, restore motor function, and improve the quality of life t...

The increasing complexity of Internet-of-Things (IoT) applications and near-sensor processing algorithms is pushing the computational power low-power, battery-operated end-node systems. This trend also reveals growing demands for high-speed energy-efficient inter-chip communications to manage amount data coming from off-chip sensors memories. While traditional micro-controller interfaces such a...
