    摘要

    The paper presents a dual-band switchable low noise amplifier implemented in 0.25-μm CMOS technology for 5-GHz wireless multimedia applications. The high-speed wireless multimedia applications call for broadband design techniques for RF circuits. Instead of using conventional broadband techniques not well suitable for CMOS implementation, a dual-band switchable load is proposed for broadband LNA design. The dual-band switchable load enables the LNA operate at the lower or the upper band at 5-GHz band by a 1-bit control signal. The LNA exhibits over 17 dB power gain, 3.5 dB noise figure and input 1-dB compression point -23dBm in both frequency bands. It draws 9.5mA from 2.5V supply. The power gain remains larger than 16 dB as temperature varies from -5 to 65°C.
