  • Publication number: 20080211470
    Abstract: The present invention discloses an auto discharge linear regulator comprising: a basic linear regulator for converting an input voltage to an output voltage at an output node; a load detector circuit for detecting the load condition at the output node; and an discharge control circuit under control by the load detector circuit for discharging the voltage at the output node.
    Type: Application

  • Publication number: 20080174286
    Abstract: A quick response switching regulator comprises a power stage having a pair of high-side switch and low-side switch and an inductor connected together by a switching node, a feedback circuit for producing a feedback signal, and a control circuit producing control signals with reference to the feedback signal to control the pair of high-side switch and low-side switch. The feedback circuit is connected to the switching node to shorten the feedback path and speed up the response. The control circuit further monitors the current flowing through the inductor to keep the low-side switch off before the peak of the inductor current becomes higher than a value.

  • Patent number: 6230177
    Abstract: The method and apparatus employ a texture filter in a graphics processor to perform a transform such as, for example, a Fast Fourier Transform. The texturizer can include an array of linear interpolators. The architecture reduces the computational complexity of the transform processes.
