    摘要: A phase locked loop (PLL) circuit, comprises a frequency integrator circuit that receives a target signal, a phase shift signal and a frequency gain correction parameter and that selectively disables tracking frequency offset based on a value of the frequency gain correction parameter. A phase integrator circuit communicates with frequency integrator circuit, that synchronizes phase with the target signal and generates a phase signal. A phase shift measurement circuit generates the phase shift signal based on the phase signal. A phase interpolator circuit generates the frequency gain correction parameter based on the phase signal.

    摘要: In a precompensation circuit for magnetic recording of data signals, a clock produces clock signals at a predetermined rate to clock the recording of the data signals. A clock delay generator generates clock delay data relative to the generated clock signals for successive data signals to be recorded. The clock delay data for each data signal is formed according to the states of a set of adjacent data signals. n>1 programmable clock delay units operate sequentially to control the recording times of the successive data signals. Each clock delay unit receives the clock delay data for one data signal in each sequence of n successive data signals and determines recording time of the one data signal according to the clock delay data for the one data signal in the sequence.

    摘要: A self-reparable semiconductor includes multiple functional units that perform the same function and that include sub-functional units. The semiconductor includes one or more full or partial spare functional units that are integrated into the semiconductor. If a defect in a sub-functional unit is detected, then that sub-functional unit is switched out and replaced with a sub-functional unit in the full or partial spare functional unit. The reconfiguration is realized with switching devices that are associated with the sub-functional units. Defective functional or sub-functional units can be detected after assembly, during power up, periodically during operation, and/or manually.
