摘要： A method and apparatus for dynamically adjusting power of a transmitter is herein described. A transmitter transmits a pattern to a receiver at a differential voltage. The length of the pattern, in one embodiment, is selected to be a reasonable length training pattern, as not to incur an extremely long training phase. If errors are detected at the receiver in the pattern, the transmitter steps the differential voltage until errors are not detected in the pattern at the receiver. The differential voltage, where no errors are detected, is scaled by a proportion of a target confidence level to a measured confidence level associated with the reasonable length training pattern. As a result, a training phase is potentially reduced and power is saved while not sacrificing confidence levels in error rates in the data exchange between the transmitter and receiver.

摘要： An apparatus and a method for active case cancellation for an inductor/capacitor network have been presented. One embodiment of the method includes generating a derivative of an input to a die from a package, the derivative being out of phase relative to the input. The method further comprises substantially canceling resonance between an inductance of the package and a capacitance of the die with the derivative.

摘要： In some embodiments, a chip includes first and second nodes, a variable voltage source, a transmitter, change detection circuitry, and control circuitry. The transmitter includes a driver coupled to the first and second nodes, and first and second resistive structures coupled between the first and second nodes, respectively, and the variable voltage source. The change detection circuitry detects changes in voltages of the first and second nodes following a change in voltage of the variable voltage source. The control circuitry determines whether the changes in voltages of the first and second nodes are consistent with the transmitter being coupled through interconnects to a remote receiver. Other embodiments are described and claimed.

摘要： A multi-axial position sensor assembly for a joystick in which sensor/magnet pairs are positioned orthogonally on concentric gimbal rings such that each sensor and corresponding magnet pivot in relation to each other as a result of joystick movement. The sensors produce a reference output voltage when the joystick is centered and the sensors are aligned with the magnets. As a magnet rotates in relation to a sensor, the sensor produces an output voltage which is proportional to the angle of rotation and which has a polarity dependent upon the direction of rotation relative to the centered position.
