An analog FPGA is best understood as a field-programmable analog array, or FPAA, which brings hardware reconfigurability to analog signal processing. This guide explains how FPAAs work, how they compare with digital FPGAs, and where programmable analog fits in modern embedded and mixed-signal systems.

Okika Devices has expanded its Chameleon™ platform with new 4th-order Butterworth low-pass filter modules and the Chameleon™ Programming Board. The new filters complement the existing 8th-order Chameleon options, while the programming board enables engineers to develop and test custom FPAA configurations. Together, the additions broaden the platform for both ready-to-use filtering and programmable analog development.

Modern embedded systems rarely choose between analog and digital processing alone. This article compares fixed analog front ends, programmable AFEs, FPAAs, ADCs, and DSPs to show how hybrid architectures can improve signal quality, flexibility, latency, and data efficiency.

Good ADC performance starts before the signal reaches the converter. Learn how gain, filtering, level shifting, impedance matching, and protection help preserve signal integrity, improve measurement accuracy, and make better use of an ADC’s available range and resolution.

Explore how FPAAs enable sensor-level intelligence, analog feature extraction, and edge autonomy in military autonomous systems and defense robotics.

Modern defense systems demand flexibility across the entire signal chain, not just in software and digital hardware. FPAAs provide a way to reconfigure analog processing without replacing hardware. This approach can help improve adaptability, sustainment, and system longevity.

Learn how FPAAs help engineers build flexible sensor interfaces, improve ADC performance, reduce redesign cycles, and process signals closer to the source.
