Abstract: Technologies are described herein for adaptive spread-spectrum clocking to limit interference in a target band. Interference in the target band may be reduced by changing the frequency of the clock signal at a higher modulation rate for clock frequencies that interfere with, or are correlated to, the target band and changing the frequency of the clock signal at a lower modulation rate for the clock frequencies that are not correlated to the target band.

Abstract: A circuit may be configured to reduce voltage dip or overshoot that can occur on power supply lines when current loads are turned on or off more quickly than a power supply can respond. The circuit can be configured to generate a compensation voltage that can be coupled into the supply lines when the current load changes.

Abstract: A POR circuit includes a voltage divider coupleable between a supply voltage and a POR trace, including a first element coupled between the supply voltage and a node, and a second element coupled between the node and the POR trace. A switch is drain to source coupled between the POR trace and a reference voltage. A first decoupling capacitor is coupled between the POR trace and the reference voltage. A second decoupling capacitor is coupled between the node and the reference voltage. ESD protection for an integrated circuit includes charging a node of a voltage divider coupled between a supply voltage and a POR trace to a predetermined percentage of the supply voltage, decoupling high frequency noise with a first decoupling capacitor between the POR trace and a reference voltage, and decoupling low frequency noise with a second decoupling capacitor between the node and the reference voltage.

Abstract: Technologies are described herein for adaptive brownout detection and mitigation in a storage device having rotational storage media. A target position on the rotational storage media for a current write operation is received. A value for a brownout mitigation parameter is determined based on the target position. A brownout condition is then detected on the storage device, and upon detecting the brownout condition, the current write operation is completed before a power-on reset of the storage device.
