A 3.1-5GHz High and Flat Gain UWB LNA

摘要：

A 3.1-5 GHz Ultra Wideband (UWB) CMOS low noise amplifier (LNA) with high gain and noise cancellation is presented. The LNA is composed of two stages–an input common-gate stage with a resonant load at 3.1GHz, driving a common source stage with a resonant load of 5GHz. Noise cancellation is achieved through the forward feedback technique, and an output buffer has been added for test purposes. The amplifier has been designed in a 0.65 nm CMOS process, and has a power gain of 21 dB that varies less than 0.5dB across the 3.1-5 GHz band with a noise figure of less than 5.4 dB. The LNA consumes 8 mA of current from 1 V power supply and occupies 0.24 mm2 of chip area.
