Abstract:
1. An adaptive dynamic voltage scaling circuit, including: (a) a primary variable voltage source for providing an initial circuit voltage; (b) at least one variable voltage source powered by the primary variable voltage source; (c) at least one test cell including: (d) a comparison and detection circuit coupled to at least one variable voltage source and at least one test cell, for comparing the functionality of the at least one test circuit within a coupled test cell against the functionality of the at least one associated reference circuit within such coupled test cell over a range of voltage values from the variable voltage source associated with such test cell until a cross-over voltage value is determined at which the at least one test circuit reaches a cross-over point of functionality; and (e) a controller circuit coupled to the comparison and detection circuit for adjusting the voltage of the primary variable voltage source to be marginally greater than the cross-over voltage value.
