Field Programmable Analog Arrays (FPAAs) and its design software has introduced two new capabilities to the analog world. The first is the ability to translate complex analog circuits to a simple set of low-level functions, and thus to give designers the analog equivalent of an FPGA. The second is the ability to place analog functions under real-time software control within the system.
...and analog will never be the same again.

ni2designs introduces ANALOGIC programmable analog prototyping board to accelerate design cycles and keep system designers competitive.
ANALOGIC Protoboard is used for prototyping analog based designs using Field Programmable Analog Arrays (FPAA) technology. By providing the analog equivalent of logic gates, FPAAs give designers the ability to describe analog functions such as gain stages and filters without reference to the underlying function - in other words, without having to think on the level of such components as op amps, capacitors,
resistors, transconductors, and current mirrors. Lifted to this higher level of abstraction, the design process becomes so simple that non-specialists can create sophisticated circuits that would require weeks or months of design work with ASICs or discretes.
The ANALOGIC Protoboard fully integrates an FPAA based system, giving you the power to implement analog functions in reconfigurable hardware and to update the functions from within the software.
