    摘要: A method of manufacturing an electrical system for reducing differential-to-differential far end crosstalk (DDFEXT) includes converting a first S parameter representative of a design of a first electrical system into a differential-only S parameter, generating a second differential-only S parameter configured to add even-mode propagation delay and odd-mode propagation delay of the differential-only S parameter of the electrical system such that a total even-mode propagation delay and odd-mode propagation delay of the differential-only S parameter are substantially equivalent, and reconfiguring a second electrical system from the differential-only S parameter and the second differential-only S parameter.

    摘要: The disclosure provides for a slope voltage compensation circuit with an adaptive slope compensation method, in a DC-DC switching converter operating in current control mode, at duty cycles greater than 50%. The proposed solution allows for the dynamic range of useful operation to be extended, lowering the slope voltage compensation at the beginning of the cycle, and then increasing the compensation as 50% duty cycle is achieved. This method is based on voltage control instead of time, and a second phase of a clock is not required.

    摘要: A voltage generating circuit including a pre-driving unit and a voltage generating unit is provided. The pre-driving unit receives an oscillation signal and enhances a driving capability of the oscillation signal to generate a pre-driving signal. The voltage generating unit receives an input signal and the pre-driving signal, and generates an output signal according to the input signal and the pre-driving signal. The voltage generating unit generates a voltage signal according to the pre-driving signal. One of the pre-driving unit and the voltage generating unit adjusts a slew rate or a ringing component of the voltage signal by using the pre-driving signal. A pre-driving signal generating module for driving a voltage generating circuit is also provided.
