What is an FPAA?
A Field Programmable Analog Array (FPAA) is the analog equivalent of an FPGA.
Instead of programming digital logic, engineers configure analog circuits such as:
- Filters
- Amplifiers
- Signal conditioning blocks
- Sensor interfaces
Using software, these analog circuits can be reconfigured instantly, allowing students and researchers to prototype and experiment without redesigning hardware. For teaching and research environments, this means:
- Faster experimentation
- Fewer hardware boards required
- Reusable laboratory equipment across multiple courses
Why FPAAs for Education
Hands-On Learning
Teach core concepts in analog design, signal processing, and embedded systems with hardware students can configure and test in minutes. Students can directly observe how circuit parameters affect real-world signals.
Flexible and Cost-Effective
Replace multiple dedicated analog boards with one reconfigurable platform, ideal for classrooms and laboratories with limited budgets. A single FPAA platform can support many different laboratory exercises.
Accessible at Every Level
From introductory undergraduate labs to graduate research and thesis projects, FPAA systems scale with your program.
Students can begin with simple experiments and progress toward complex system-level designs.
