Abstract

We describe a set of basic circuit building blocks for computation using an analog temporal step function representation for the inputs and outputs. Methods for computing weighted averages and thresholded differences are described. These techniques have advantages as CMOS process technologies scale since they minimize the analog circuitry required. We show an example of a time-based edge detector that directly interfaces to the output of a time-to-first spike imager.
