Field-programmable analog arrays (FPAAs) providea method for rapidly prototyping analog systems. Currently available commercial and academic FPAAs are typically based on operational amplifiers (or other similar analog primitives) with only a few computational elements per chip. While their specific architectures vary, their small sizes and often restrictive interconnect designs leave current FPAAs limited in functionality and flexibility. For FPAAs to enter the realm of large-scale reconfigurable devices such as modern field-programmable gate arrays (FPGAs),new technologies must be explored to provide area-efficient accurately programmable analog circuitry that can be easily integrated into a larger digital/mixed-signal system. Recent advances in the area …

Many curricula include separate classes in both digital signal processing (DSP) theory and very high-speed integrated circuit hardware description language (VHDL) modeling; however, there are few opportunities given to students to combine these two skills into a working knowledge of DSP hardware design. A pedagogical framework has been developed whereby students can leverage their previous knowledge of DSP theory and VHDL hardware design techniques to design, simulate, synthesize, and test digital signal processing systems. The synthesized hardware is implemented on field-programmable gate arrays (FPGAs), which provide a fast and cost-effective way of prototyping hardware systems in a laboratory environment. This …

Field-programmable analog arrays (FPAAs) provide a method for rapidly prototyping analog systems. While currently available FPAAs vary in architecture and interconnect design, they are often limited in size and flexibility. For FPAAs to be as useful and marketable as modern digital reconfigurable devices, new technologies must be explored to provide area efficient, accurately programmable analog circuitry that can be easily integrated into a larger digital/mixed signal system. By leveraging recent advances in floating gate transistors, a new generation of FPAAs are achievable that will dramatically advance the current state of the art in terms of size, functionality, and flexibility.
