Book Description
Large-scale reconfigurable and programmable analog devices provide a new option for prototyping and synthesizing analog circuits for analog signal processing and beyond. Field-programmable analog arrays (FPAAs) built upon floating gate transistor technologies provide the analog reconfigurability and programmability density required for large-scale devices on a single integrated circuit (IC). A wide variety of synthesized circuits, such as OTA followers, band-pass filters, and capacitively coupled summation/difference circuits, were measured to demonstrate the flexibility of FPAAs. Three generations of devices were designed and tested to verify the viability of such floating gate based large-scale FPAAs. Various architectures and circuit topologies were also designed and tested to explore the trade-offs present in reconfigurable analog systems. In addition, large-scale FPAAs have been incorporated into class laboratory exercises, which provide students with a much broader range of circuit and IC design experiences than have been previously possible. By combining reconfigurable analog technologies with an equivalent large-scale digital device, such as a field-programmable gate array (FPGA), an extremely powerful and flexible mixed signal development system can be produced that will enable all of the benefits possible through cooperative analog/digital signal processing (CADSP).

Book Description
Field-programmable analog arrays (FPAAs) provide a 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, flexibility, and usefulness. Recent advances in the area of floating-gate transistors have led to an analog technology that is very small, accurately programmable, and extremely low in power consumption. By leveraging the advantages of floating-gate devices, a large-scale FPAA is designed that dramatically advances the current state of the art in terms of size, functionality, and flexibility. A large-scale FPAA is used as part of a mixed-signal prototyping platform to demonstrate the viability and benefits of cooperative analog/digital signal processing. This work serves as a roadmap for future FPAA research. While current FPAAs can be compared with the small, relatively limited, digital, programmable logic devices (PLDs) of the 1970s and 1980s, the floating-gate FPAAs introduced here are the first step in enabling FPAAs to support large-scale, full-system prototyping of analog designs similar to modern FPGAs.

Book Description
Field-programmable analog arrays (FPAA) are integrated circuits with a collection of analog building blocks connected through a wire and switch fabric to achieve reconfigurability similar to the FPGAs of the digital domain. Like FPGAs, FPAAs can help reduce the time and money costs of the integrated circuit design cycle and make analog design much easier. In recent years, several types of FPAAs have been developed. Among these, FPAAs that use floating-gate transistors as programming elements have shown great potential in scalability because of the simplicity they provide in configuring the chip. Existing tools for programming FPAAs tend to be device specific and aimed at specific tasks such as filter design. To move FPAAs to the next step, more powerful and generic placement and routing tools are necessary.

Book Description
Neuromorphic electronic engineering takes its inspiration from the functioning of nervous systems to build more power efficient electronic sensors and processors. Event-based neuromorphic systems are inspired by the brain's efficient data-driven communication design, which is key to its quick responses and remarkable capabilities. This cross-disciplinary text establishes how circuit building blocks are combined in architectures to construct complete systems. These include vision and auditory sensors as well as neuronal processing and learning circuits that implement models of nervous systems. Techniques for building multi-chip scalable systems are considered throughout the book, including methods for dealing with transistor mismatch, extensive discussions of communication and interfacing, and making systems that operate in the real world. The book also provides historical context that helps relate the architectures and circuits to each other and that guides readers to the extensive literature. Chapters are written by founding experts and have been extensively edited for overall coherence. This pioneering text is an indispensable resource for practicing neuromorphic electronic engineers, advanced electrical engineering and computer science students and researchers interested in neuromorphic systems. Key features: Summarises the latest design approaches, applications, and future challenges in the field of neuromorphic engineering. Presents examples of practical applications of neuromorphic design principles. Covers address-event communication, retinas, cochleas, locomotion, learning theory, neurons, synapses, floating gate circuits, hardware and software infrastructure, algorithms, and future challenges.

Book Description
With the introduction of the floating-gate transistor into reconfigurable architectures, great advances have been made in the field. Recently, Hall et. al. have proposed the first truly large-scale field programmable analog array (FPAA). As an outgrowth of this work, a new class of FPAAs based on translinear elements has begun to be developed. The use of translinear elements, multiple input translinear elements (MITEs) specifically, allows for extreme versatility in the functions implemented by the system while keeping the computational elements of the FPAA regular. In addition, synthesis procedures have been developed for translinear elements. This facilitates the implementation of large-scale systems on the FPAA because the circuit design can be extracted using the synthesis procedures based on equations entered by the user. Two architectures are proposed for the new FPAA. The first architecture uses fine grain reconfigurability, every gate capacitor and the drain of each MITE can be connected arbitrarily, in order to create reconfigurable MITE networks. Circuits including a squaring circuit, a square root circuit, a translinear loop, a vector magnitude circuit, and a 1st-order log-domain filter were implemented using this architecture and results are presented. In addition, examples are shown to illustrate the compilation of the circuits onto the FPAA. The second proposed architecture uses a mix of fine and medium granularity in order to simplify the implementation of larger systems. Examples are given and again the compilation of the circuits onto the FPAA is shown.
