摘要： Methods and apparatus relating to a low ripple mechanism of mode change in switched capacitor voltage regulators are described. In an embodiment, a mode change of a Switching Capacitor Voltage Regulator (SCVR) is caused based at least in part on a comparison of an output voltage of the SCVR and a reference voltage. The output voltage is sensed based at least in part on a clock signal. Other embodiments are also disclosed and claimed.

摘要： An apparatus is provided which comprises: at least two switches in series between an input voltage node and a ground terminal; an inductor coupled between a mid-point of the at least two switches and an output terminal; a first circuitry to compare a current through the inductor with a threshold current, and to control one or both of the at least two switches, based at least in part on the comparison; and a second circuitry to randomly vary the threshold current over consecutive cycles of switching of the at least two switches.

摘要： Methods and apparatus relating to low cost and/or low overhead serial interface for power management and other IC (Integrated Circuit) devices are described. In an embodiment, a unique address is assigned to each of a plurality of slave devices. The plurality of slave devices are coupled in a daisy chain configuration. And, any access directed at a first slave device from the plurality of slave devices is allowed based at least in part on comparison of an address of the first slave device and an address associated with the access. Other embodiments are also disclosed and claimed.

摘要： Methods and apparatus relating to reducing switching noise and improving transient response in voltage regulators are described. In an embodiment, one or more pulses are inserted into an output waveform of a voltage regulator. The one or more pulses introduce multiple frequencies into the output waveform of the voltage regulator (e.g., to reduce acoustic noise). In another embodiment, the output voltage of a voltage regulator is modified in response to comparison of the output voltage with at least one of a plurality of threshold values. The plurality of threshold values includes an upper trigger point voltage value and a lower trigger point voltage value. Other embodiments are also disclosed and claimed.
