An SRAM based field programmable analogue array

Systems designers have not, in the past, been provided with families of field programmable components in the same way as digital designers. the reasons for this are many - analogue design is a hard discipline and the variety of circuit elements are large. In this feature, a field programmable analogue array (FPAA) and its design software is described, The array uses a switched capacitor based architecture, and to deskill the design task it provides a drag-and-drop GUI accompanied by a library of analogue IP modules.
