摘要： Inter-device adaptable interfacing clock skewing. The invention is operable in either one of both of a transmit mode and a receive mode to perform skewing of a transmitted and/or a received signal. The operational parameters including frequency and phase may be determined during auto detect/auto negotiation, they may be programmed externally, or they may be user selected in various embodiments. A device may include a clock generator, one or more divider, and one or more delay cells internally to the device. If desired, a high frequency clock is generated within the device and then divided down to generate the appropriate clock signal that supports the communication and interaction between multiple devices. Registers and/or pins may be used to select the clock frequency and phase of output clock signals. The present invention supports multiple Ethernet protocols between multiple devices including 10BaseT, 100BaseT, and 1000BaseT.

摘要： The present invention is directed to an apparatus and method for reducing a parasitic capacitance in an integrated circuit. The apparatus includes a substrate and a biasing device. The substrate has a circuit disposed thereon, wherein a first capacitance exists between the substrate and an element of the circuit. The biasing device DC biases a first portion of the substrate to a voltage different than a voltage of a second portion of the substrate, thereby inducing a second capacitance between the first portion of the substrate and the second portion of the substrate. The second capacitance is in series with the first capacitance.
