摘要： A slew rate regulation circuit varies a slew rate of a waveform of a voltage outputted to a DC motor through a N-channel MOSFET. The slew rate regulation circuit lowers a peak level by dispersing frequency components of switching noise, which develops in a frequency range higher than a frequency range determined by a carrier frequency.

摘要： A method an apparatus for a power switch acceleration scheme during wakeup is disclosed. In one embodiment, an integrated circuit includes at least one power gated circuit block. The power gated circuit block includes a virtual voltage node from which a voltage is provided to the circuitry of the block when active. Power switches are coupled between the virtual voltage node and a corresponding global voltage node. When the power gated circuit block is powered on, power switches are activated sequentially. The rate at which power switches are activated is increased as the voltage on the virtual voltage node increases. Sequentially activating the power switches may prevent an excess of current inrush into the power gated circuit block. The increase in the rate at which power switches are activated when the voltage on the virtual voltage node is at least at a certain level may allow for a faster wakeup.
