Current-mode amplifier/integrator for a field-programmable analog array

An electronically-programmable analog circuit (EPAC), based on the switched-capacitor (SC) technique, is an analog counterpart of digital FPGAs. The full speed potential of analog circuits, however, can be utilized only by continuous-time (CT) field-programmable analog arrays (FPAAs). In this paper...

Description
Summary:An electronically-programmable analog circuit (EPAC), based on the switched-capacitor (SC) technique, is an analog counterpart of digital FPGAs. The full speed potential of analog circuits, however, can be utilized only by continuous-time (CT) field-programmable analog arrays (FPAAs). In this paper an example of an FPAA structure with local interconnections is shown. Each cell derives a weighted sum of selected signals from four nearest neighbors, and optionally performs integration (ideal or lossy) to produce its own output signal.
