摘要： A control device for fast transient recovery of the output voltage of DC-DC converters. The control device is characterized by using a dual-threshold method to compare the actually received loading voltage values on the loading terminals of DC-DC converters, i.e., a total of four threshold levels including a negative-ripple falling-edge threshold and a negative-ripple rising-edge threshold on the negative polarity, and a positive-ripple rising-edge threshold and a positive-ripple falling-edge threshold on the positive polarity. During the transient, the load current charging/discharging control device disclosed in the invention may be switched between charging and discharging mode based on the relation between two-pairs threshold values and output voltage amplitude of DC-DC converters. This mechanism may allow DC-DC converters with higher slew rate to make transient ripples on output voltage to return to steady state more quickly.

摘要： A cascode-cascade power amplifier assembly is provided. Which includes a first common-source amplifier, a second common-source amplifier, a phase shift matching network coupled to the first common-source amplifier and the second common-source amplifier for providing a 90-degree phase shift and allowing less than 50% of the output power of the first common-source amplifier to be transmitted to the second common-source amplifier, a common-gate amplifier which forms a series circuit arrangement with the first-common source amplifier and a parallel circuit arrangement with the second common-source amplifier, and an equivalent quarter-wave or three-quarter wave circuit which forms a series circuit arrangement with the common-gate amplifier and a parallel circuit arrangement with the second common-source amplifier. According to the present invention, the first common-source amplifier and the common-gate amplifier form a cascode main amplifier, while the first common-source amplifier and the second common-source amplifier form a cascade auxiliary amplifier.
