OSLO

Process: CMOS AMS 0.35μm
Date: 07/2011
Size: 1600*1600μm2 without pads
Designer: Guillaume Arnaud
Description: The ASIC "OSLO" is dedicated to the on-line detection of neural action potential (spikes) that convey information for in vitro excitable cells. OSLO computes in analog mode a detection threshold of the spikes; this threshold is servoed to the standard deviation of the input signal (neural signal). OSLO output stage encodes spike events in asynchronous binary mode. OSLO is a test device; further prototypes should be embedded in microsystems or implants.

MINUS

Process: AMS 0.35um 2P4M CMOS process
Date: 07/2010
Size: 3000 * 3000 μm2 without pads
Designer: Adeline Zbrzeski
Description: Medical Interface for NeUronal Stimulation is dedicated to acquisition of low-amplitude neuronal signals, and adapted stimulation. The device includes different amplifiers and filters for test and characterization.
