    摘要: Angular displacement of a flexible substrate is determined based on an electrical change of a mm-wave circuit associated with the flexible substrate. This electrical change may relate to, for example, one or more of a phase shift, an amplitude shift, a frequency shift, or a pulse shift. In some implementations the flexible substrate may include conductors on multiple layers whereby an angular displacement of the flexible substrate causes a relative displacement between conductors of different layers, thereby inducing the electrical change of the mm-wave circuit.

    摘要: A communication channel includes a first component having a transmitter coupled to a normal signal source, and a second component having a receiver coupled to a normal signal destination. A communication link couples the first and second components. Calibration logic provides for setting an operation value for a parameter of the communication channel, such as by executing an exhaustive calibration sequence at initialization of the link. A tracking circuit, including a monitoring function, tracks drift in the parameter by monitoring a feedback signal that has a characteristic that correlates with drift in the communication channel, and updates, or indicates the need for updating of, the operation value of the parameter in response to the monitoring function.

    摘要: A circuit, system and method adjusts a reference voltage, such as an internal or external reference voltage VREF, in response to a first voltage at a first contact, such as a pin on a memory controller used for reading or writing data, and a second voltage at a second contact in embodiments. Logic is coupled to the first and second contacts to provide a control signal in response to the first and second voltages. A comparator provides an input signal to the logic in response to a target reference voltage and the reference voltage during a calibration or initialization mode of operation. In an alternate embodiment, a plurality of data values at a first contact are compared to a predetermined plurality of test data. An up/down signal is then provided to a counter and a register stores a counter value used to provide a reference voltage.
