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.

Certain aspects of a method and system for a compact and power efficient local oscillator generation architecture in multi-standard systems may include selection of an input frequency range of operation at a voltage controlled oscillator (VCO) based on a particular wireless band of operation. An image rejection mixer may be enabled to mix a plurality of generated local oscillator signals. An inductive buffer may be enabled to generate an output signal by buffering the mixed plurality of generated local oscillator signals in a single backend stage. An in-phase (I) component and a quadrature (Q) component of the generated output signal may be generated by utilizing an RC-CR quadrature network.
