    摘要: A system includes a constant input current filter configured to draw a constant input current from a power source and to generate a variable output current. The constant input current filter includes a capacitor, a boost converter, and a buck converter. The boost converter is configured to receive at least a portion of the input current and to charge the capacitor using at least the portion of the input current during first time periods associated with operation of a load. The buck converter is configured to discharge the capacitor and to provide an additional current as part of the output current during second time periods associated with operation of the load. The load could represent an electronic device having a time-varying output power characteristic, such as a wireless radio.

    摘要: An optical switch with a plurality of actuators includes a controller configured to control the operation of a plurality of channels, where each channel has at least one electrical driver and at least one actuator, by interleaving periods of voltage switching output with periods of no voltage switching output for one or more drivers whilst the output voltage is switching from one level to another level. Alternatively, an optical switch with a plurality of actuators comprises a controller configured to control the operation of a plurality of channels, where each channel has at least one electrical driver and at least one actuator, by switching the output voltage from one level to another level for at least one driver of a first channel whilst at least one oilier driver of at least one other channel is in a relatively high impedance mode.

    摘要: Examples are disclosed for switching frequency control of an on-chip or integrated voltage regulator. In some examples, a switch frequency of an integrated voltage regulator may be monitored. A determination of whether the monitored switch frequency causes radio signal interference may cause the switch frequency to be adjusted to eliminate or reduce the radio signal interference. Other examples are described and claimed.
