At the heart of Argo lies a custom CMOS array of low–noise, high–speed amplifiers.
Supporting this CMOS is essentially a miniaturized data center. It handles the 30 Gb/s data stream produced by the full frame, 39 kHz, 256 x 256 channel CMOS.
Digitization of this data is performed by 32x, 12–bit, 80 MSa/s ADCs and encoded by an FPGA which communicates with a performance PC over a single optical fiber bundle.

Microwire electrodes have been a staple in neural recording since the 1950s. Their low cross-sectional area and long aspect ratio allow them to insert into tissue and record extracellular action potential waveforms in close proximity to neurons. So why aren't microwire-based BMI ubiquitous? The answer is scalability. Manually connecting even tens of microwires to electronic amplifiers is an arduous task.
Different experiments need different bundles. Argo has been designed to facilitate quick interchange of bundles via a modular, removable headstage. We provide a custom range of bundles with varying number, wire type and pitch.
|Bundle Size||100–65k individual electrodes|
|Electrode Spacing||50–200 µm|
|Electrode Diameter||10–40 µm|
