Multiplexed active biologic array
CA 2259406 A1
An improved biologic electrode array (12) and methods for using the same. Each electrode (30) in the array (12) is coupled to a respective sample-and-hold circuit (26). The electrodes (30) and sample-and-hold circuits (26) are integral and form an array (12) within a single semiconductor chip, such that each sample-and-hold circuit (26) may be loaded (37) with a predefined voltage provided by a single, time-shared digital-to-analog converter (DAC) (22). All of the sample-and-hold circuits (26) may be accessed through a multiplexer which may scan through some or all of the electrode locations (30). Each sample-and-hold circuit (26) may comprise a capacitor (32) and one or more transistor switches (34, 36), the switches (34, 36), when closed providing electrical communication between the capacitor (32) and a source line (37) formed in the matrix (12).
