Abstract
A bistable cell includes a pair of inverters and multiple pairs of cross-coupled tristate buffers. Each pair of tristate buffers can be individually selected to implement an entropy harvesting state for the bistable cell. Each of the tristate buffers generally has lower strength than the inverters but the inverter-to-buffer strength ratio can be configured through selective use of one or more of the tristate buffer pairs. The resulting entropy harvesting state behavior can be varied based on the inverter-to-buffer strength ratio in terms of greater randomness of the output bits or decreased power consumption.
