Okika Devices pioneers reconfigurable analog technology that allows engineers to design smaller, lower-power, lower-cost analog systems with greater flexibility.


As the global leader in Field Programmable Analog Arrays (FPAAs), Okika Devices provides the chips, development platforms, and software tools needed to rapidly build and iterate custom analog systems. Unlike fixed-function analog hardware, FPAAs can be reprogrammed in real time, enabling faster prototyping, adaptive signal processing, and accelerated product development without the expense and delays of fabricating new ASICs.

What is a Field Programmable Analog Array?

A Field Programmable Analog Array works like a digital FPGA for analog circuits. Instead of digital logic gates, FPAAs use configurable analog blocks like operational and differential amplifiers with capacitor arrays that can be programmed as internal resistors or capacitors. You can connect and program these blocks with Okika’s analog software cores to create analog signal processing functions for applications such as sensor interfacing, audio processing, industrial controls, and low-power analog computing.
