摘要： A device includes a first inductor positioned on a first substrate. The first inductor has at least one turn in a plane that is perpendicular to a plane of the first substrate. The first inductor is positioned for near field coupling with a second inductor. The second inductor is positioned on a second substrate, with at least one turn that is in a plane perpendicular to a plane of the second substrate. The second inductor is substantially parallel to the first inductor. Such an arrangement may be used for near field coupling, including edge-to-edge coupling, between two integrated circuits.

摘要： The present disclosure provides a system, circuit, and method for correcting clock skew in time-interleaved analog-to-digital converters. At least two clock signals are received along respective channels. A delay of a first channel, carrying a first clock signal, is accounted for by applying one or more first adjustment factors to the channels until an edge of the first clock signal is aligned with a transition point of a reference signal. The first clock signal is swapped to the second channel, and vice-versa. A value of the reference signal as sampled by the first clock signal is compared to values of the reference signal as sampled by the second clock signal to determine a skew of the second channel vis-à-vis the first channel, and one or more second adjustment factors are applied to the second channel based on the determined skew of the second channel.

摘要： A built-in self test for receiver operation is provided through a testing method that evaluates characteristics of a received signal eye diagram. The receiver receives a serial data signal and applies compensation to that received serial data signal to generate a compensated serial data signal. The properties of an eye diagram associated with the compensated serial data signal are measured. In this context, certain desired eye diagram properties are characterized by parameters indicative of pass/fail criteria for receiver testing. The measured eye diagram properties are then compared against the parameters. A receiver testing conclusion signal is then output based on results of the comparison.
