This paper presents the design of a reconfigurable low noise amplifier (LNA) for multi-standard multi-band receiver. In this design, inductively-degenerated common-source (IDCS) topology is chosen as it has been proven to be a good choice in designing multi-standard multi-band LNA. The design is using 0.18 μm CMOS technology. The reconfigurable LNA has been designed to operate in two bands of standards consisting the bands range from 800 to 1000-MHz (lower band) and 1800 to 2200-MHz (upper band). The simulation results exhibit gain S21 of 12.9-dB for lower band and 12.4-dB for upper band, input reflection S11 of -14.5-dB and -17.2-dB for both bands, and output return loss S22 of -14.7-dB and -26-dB for lower and upper band making the LNA suitable for most of the mobile communication applications. The LNA also exhibits the noise of figure of 2.55-dB and 2.3-dB for lower and upper band respectively. The circuit consumes 26.5 mW when operating in lower band mode and uses 18.8 mW of power when operating in upper band mode.
