Abstract :
A wideband 1.1-1.7GHz low-noise amplifier (LNA) for dual-band global positioning system (GPS)receiver is presented.It is a single-ended amplifier with differential double-ended output. Input matching is extended to wide bandwidth using an input three-section band-pass Chebyshev filter. The LNA,integrated in SMIC 0.18μm CMOS process with a bandwidth of 1.1-1.7GHz, exhibits a power gain of more than 14 dB, an input match of less than -10dB over the band, a minimum noise figure of 3.2dB and a 1dB compression point of -6.35dBm. The LNA consumes 18mA from a 1.8V supply voltage.
