摘要： An impedance matching network is integrated on a first die and coupled to a second die, with the first and second dies mounted on a conductive back plate. The impedance matching network comprises a first inductor bridging between the first and second dies, a second inductor coupled to the first inductor and disposed on the first die, and a metal-insulator-metal (MIM) capacitor disposed on the first die. The MIM capacitor has a first metal layer coupled to the second inductor, and a second metal layer grounded to the conductive back plate. A method for manufacturing the integrated impedance matching network comprises the steps of forming an inductor on a die, forming a capacitor on the die, coupling the capacitor to the inductor, coupling the die bottom surface and the capacitor to a conductive plate, and coupling the inductor to another inductor that bridges between the die and another die.

摘要： A resonant power converter is disclosed with a driving circuit generating a switching signal connecting power to a resonant tank circuit, with a voltage monitoring circuit measuring a voltage output and a load current. A micro-controller is operable with a control circuit for multiple step sampling with the switching signal at a switching frequency to settle the resonant circuit determined from the voltage output and load current. A fast load transient response at a high frequency with the resonant circuit provides the multiple step sampling to ensure enough time for micro-controller to calculate. Optimal trajectory control facilitates a burst mode of high frequency with the resonant circuit using adaptive multiple step sampling for an on-time to extend the burst operation range. A soft start-up process uses the micro-controller processing in multiple stages.
