  • Systems and methods for reduction of cross coupling in proximate signal lines
    Patent number: 8233229
    Abstract: Various systems and methods for reducing cross coupling in proximate signals are disclosed. As one example, a system for reducing cross-coupling in adjacent signals that includes an active slew rate limiter circuit is disclosed. The active slew rate limiter circuit is operable to receive an input signal, and to provide an output signal based on the input signal with a controlled slew rate. In some cases, such systems may be included within a storage device that includes a read head. In such cases, the systems may operate to assure a substantially constant power dissipation within the read head.
    Type: Grant
