Field-programmable gate arrays for prototyping digital circuits are a widely endorsed approach for reducing time-to-market. Offering similar advantages, a field-programmable analog array (FPAA) for prototyping continuous-time linear analog circuits is reported here. Conceptually, a FPAA consists of configurable analog blocks (CABS) and interconnect. The function of each CAE3 and the connections...

1 4 Proarammable Current Mirror A general configurable analog block (CAB) is presented, which consists of the programmable OTA, programmable capacitor and MOSFET switches. Using the CABs, the universal tunable and field programmable analog array (FPAA) can be constructed, which can realize many signal-processing functions, including filters. A prototype 5x8 CAB array has been fabricated. The ch...

Field programmable analog array (FPAA) is a rapidly growing technology for fast prototyping of analog signal processing systems facilitating the quick innovation at industry level with saving in terms of both time and cost. Analog signal processing is much faster and consumes less power than conventional digital signal processing, justifying the need for FPAA. Here we propose a Dual output curr...

Spacecraft require all manner of both digital and analog circuits. Onboard digital systems are constructed almost exclusively from field-programmable gate array (FPGA) circuits providing numerous advantages over discrete design including high integration density, high reliability, fast turn-around design cycle time, lower mass, volume, and power consumption, and lower parts acquisition and flig...

An open-source simulator to design and implement circuits and systems, replicating the results from the Field Programmable Analog Array (FPAA) is presented here. The fundamental components like the transistors, amplifiers and floating gate devices have been modeled based on the EKV model with minimal parameters. Systems including continuous-time filters and the analog frontend of a speech proce...

In addition to exhibiting a rich variety of bifurcation and chaos via tuning parameters, a chaotic system introduced by Sprott can be modeled and realized with a fixed main system block and many different changeable nonlinear function blocks such as piecewise-linear function, cubic function and other trigonometric functions. This system is very suitable for implementing a programmable chaos gen...
