A wideband CMOS low-noise amplifier (LNA) is proposed by using the concept of mutual coupling technique implemented through a symmetric center-tap inductor. A frequency widening network is designed with a center-tap inductor at the input and the output of an LNA to achieve bandwidth extension with a single stage amplifier. The proposed wideband low noise amplifier is implemented in the 0.18 um CMOS technology. This design obtains a bandwidth of 3–8 GHz with a power consumption of 3.77 mW from a 1.8 V supply.
