Abstract
This paper presents the structure of a current-based analog scan cell for analog and mixed-signal design-for-test. The cell uses current to represent the analog signal to be scanned and functions identically to a digital scan latch, except of course the scanned signal retains analog information. The concepts of scanning are explained using this structure, and some limitations, under experimental study at this time, are addressed. Techniques to apply this structure to continuous-time and sampled-data analog designs are described
