    摘要: In some embodiments, the invention includes a system having a clock recovery circuitry to receive a data signal and a reference clock signal and in response thereto to produce an in phase clock signal which is in phase with the data signal and mirrors frequency changes in the data signal, wherein the data signal has embedded clock information and a varying frequency. The system also includes a receiving gate to receive the data signal and the in phase clock signal and to gate the data signal to produce a gated data signal in response to the in phase clock signal. Other embodiments are described and claimed.

    摘要: In some embodiments, SSC (e.g., discrete SSC) profiles with intentional and controlled gaps may be used to mitigate interference for platform radios. Targeted frequency gaps are placed in spectrum of spread clocks and clock-derived signals where they may otherwise result in problematic RFI to a platform radio.

    摘要: Provided herein are different embodiments for performing radio frequency interference (RFI) mitigation in electronic devices such as mobile computing systems. In some embodiments, a dynamic RFI mitigation scheme allows for monitoring of wireless channels for RFI and to adaptively shift an identified RFI source (e.g., system clock) harmonics, e.g., either out of the on-channels or to a neutral position within the on-channels such as by using cost-function analysis.

    摘要: An improved voltage regulator is disclosed, which includes a pulse width modulator for generating a switching signal at a modulated frequency. A drive circuit is coupled to the output of the pulse width modulator, and a switching transistor is coupled to the output of the drive circuit and to an input voltage. The switching transistor generates an output voltage.
