A 3-5 GHz Ultra-wideband Low Noise Amplifier Employing Noise Cancellation

摘要：

A low noise amplifier (LNA) is proposed for a 3-5GHz ultra-wideband (UWB) system. The combination of a common-gate (CG) input stage and a common-source (CS) input cascode stage is exploited with a modified form of noise cancellation. The proposed LNA is implemented in a 0.18μm CMOS technology and achieves a power gain of 18dB, an average noise figure of 3.3dB, and better than -11dB of input/output matching, while consuming only 8mW at 1.8V supply. And the chip area is as small as 0.48 mm2.
