Abstract: Circuitry and methods of operating the same to delay a signal by a precise and variable amount. One embodiment is directed to a high speed delay line used in automated test equipment. The inventors have recognized and appreciated that an input signal having high data rate may be split into parallel split signals having lower data rates that are delayed in respective parallel delay paths before being combined to generate a delayed signal. One advantage of delaying a signal in such a fashion is to provide high delay line timing accuracy at high data speeds, while using a compact circuit design using circuitry components of lower bandwidth with reduced power consumption, for example by using complementary metal-oxide-semiconductor (CMOS). A further advantage is that a high speed delay line may be constructed from multiple lower data rate parallel delay lines that are modular, simplifying circuit design.

Abstract: Disclosed are method and apparatus for measuring material properties. Segmented field sensors have multiple sensing elements at different spatial geometries to capture field components having substantially different depths of penetration. These sensors are excited and measured on these different sensing elements to facilitate characterization of unknown material properties. This is illustrated in some embodiments using eddy current sensors to characterize materials that are frequency dispersive and/or do not produce a measurable phase shifts. Only a single scalar quantity may provide independent information from one or more of the sensing elements. Property estimation techniques, such as those using precomputed databases of sensor responses are used to estimate the unknown material properties.
