Abstract
CMOS microelectrode arrays allow for recording from neurons at thousands of sites. Here, we introduce the concept of a `dual-mode operation' microelectrode array, leveraging the advantages of full-frame scanning and switch-matrix array architectures into a single device. The chip was fabricated in 0.18 μm CMOS technology. Measured noise levels were 11.1 μVrms for full-frame scanning and 1.6 μVrms for switch-matrix mode at 3.3 μW and 38.1 μW per channel power consumption. Recordings of electrical activity from cultured neurons have been successfully conducted.
