Abstract
Floating-gate analog circuits are being used to implement advanced signal processing functions and are very useful for processing analog signals prior to analog to digital conversion. We present an architecture analogous to FPGA architectures for rapid prototyping of analog signal processing systems. These systems go beyond simple programmable amplifiers and filters to include programmable and adaptive filters, multipliers, gains, winner-take-all circuits, and matrix-array signal operations. We discuss architecture as well as details such as switching characteristics and interfacing to digital circuits or FPGAs.
