1-13GHz Wideband LNA utilizing a Transformer as a Compact Inter-stage Network in 65nm CMOS

초록

A low power wide-band low noise amplifier (LNA) is presented in 65 nm CMOS. A compact inter-stage network utilizing one transformer and a resistor is proposed to obtain ultra-wide bandwidth. The designed LNA achieves 1 - 13 GHz bandwidth with > 10 dB of power gain. The simulated noise figure ranges from 9.6 to 10.5 dB over 1-13 GHz with power consumption of 11mW at 1.2 V of power supply.
