Abstract:
With the need for low-power portable / autonomous sensor
systems, getting as much computation for a fixed power budget becomes more
and more critical. Analog signal processing can be a factor of 10,000 more
efficient, that is power dissipated for given computation bandwidth, than
custom digital computation for low to moderate (i.e. 6-12 bit SNR)
resolution signals. For these techniques to be viable, these analog
techniques must be programmable, and must scale in performance similar or
better than digital processing for smaller geometry devices. Analog
programmability will also have an impact on the resulting digital signal
processing circuits. Further, the potential of large-scale Field
Programmable Analog Arrays (FPAA), devices analogous to FPGAs with millions
of programmable analog parameters, opens up possibilities for a wide range
of applications, and the potential of widely available FPAA ICs makes these
approachable for a wide range of applications. Using these analog signal
processing techniques for a system design, signal compression is not only
essential for efficient transmission from the sensor, but for efficient
digital transmission between the ICs for low-power operation.
