In this paper, we develop a systematic design optimization methodology for switchable multi-band CMOS low noise amplifiers (LNA) in fully integrated multi-standard wireless receivers. We simultaneously optimize the performance of the LNA in each frequency band in order to efficiently design circuits with low noise that meet the specified impedance matching, gain, and power dissipation requirements. The results indicate that we are able to generate multi-band LNA designs with greater performance and fewer switchable components than those generated using traditional manual design techniques. Three design examples with up to 4 operating frequency bands demonstrate the versatility of the proposed method. © 2007 IEEE.
