About the Event
Last several years have seen an increasing demand for portable applications, and as a result, many applications are power constrained, including handheld and wireless applications, resulting in an ever increasing demand for increased computational resources in a constant power environment. One approach would be to consider using analog techniques, which shows order of magnitude improved power efficiencies, but lacks the programmability, configurability, and technical infrastructure that we see with typical digital techniques. Recent advances in analog signal processing, neuromorphic engineering, and programmable / configurable analog approaches seem to have bridged these gaps, and as a result could launch an exponential growth in analog computation that we saw in in digital IC design over 30 years ago. We will start with a short history on how digital circuits progressed from a circuit centric technology to a very high-level system technology. We will notice that a programmable digital technology overtook a relatively fixed analog technology. We will discuss how the analog circuit and signal processing techniques have progressed, including discussing our research at Georgia Tech on programmable analog circuits, programmable system design, and configurable systems. We will discuss the applications of these technologies to various applications including wireless communication, classification, image processing, and audio processing. We will then present possible roadmaps of analog signal processing technology going forward, as well as the upcoming challenges are for these approaches to reach the level of design complexity we currently expect for digital computation.
