    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.
