Discrete Double-bit Hashing
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Hashing has been widely used for nearest neighbors search over big data. Hashing encodes high dimensional data points into binary codes. Most hashing methods use the single-bit quantization (SBQ) strategy for coding the data. However, this strategy often encodes neighboring...

A low power auto-reconfigurable pipelined ADC for implantable biomedical applications
2013 Edition, November 1, 2013 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper demonstrates a reconfigurable, pipelined analog-to-digital converter (ADC) that is designed for ultra-low power consumption through the use of weak inversion region-biased transistors. In addition, the converter is able to reconfigure itself into three different modes of...
