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.
