“…The reconfigurable filters are also useful in adaptive filtering [37][38][39][40], where automatic adjustment of standard and special transfer responses is welcomed. In addition, the presented solution simplifies ways of design and the overall complexity used, for example, in [37,38]. Adaptive filtering has benefits also for the preprocessing of a signal before analogto-digital conversion [39], as well as communication systems (interference cancellation) [40].…”

The design of a low-pass-frequency filter with the electronic change of the approximation characteristics of resulting responses is presented. The filter also offers the reconnection-less reconfiguration of the order (1st-, 2nd-, 3rd- and 4th-order functions are available). Furthermore, the filter offers the electronic control of the cut-off frequency of the output response. The feature of the electronic change in the approximation characteristics is investigated for the Butterworth, Bessel, Elliptic, Chebyshev and Inverse Chebyshev approximations. The design is verified by PSpice simulations and experimental measurements. The results are also supported by the transient domain response (response to the square waveform), comparison of the group delay, sensitivity analysis and implementation feasibility based on given approximation. The benefit of the proposed electronic change in the approximation characteristics feature (in general signal processing or for sensors in particular) is presented and discussed for an exemplary scenario.

This effort develops the first rich suite of analog & mixed-signal benchmark of various sizes and domains, intended for use with contemporary analog and mixed-signal designs and synthesis tools. Benchmarking enables analog-digital co-design exploration as well as extensive evaluation of analog synthesis tools and the generated analog/mixed-signal circuit or device. The goals of this effort are defining analog computation system benchmarks, developing the required concepts for higher-level analog & mixed-signal tools to utilize these benchmarks, and enabling future automated architectural design space exploration (DSE) to determine the best configurable architecture (e.g., a new FPAA) for a certain family of applications. The benchmarks comprise multiple levels of an acoustic , a vision , a communications , and an analog filter system that must be simultaneously satisfied for a complete system.
