Previously reported wideband CMOS low-noise amplifiers (LNAs) have difficulty in achieving both wideband input impedance matching and low noise performance at low power consumption and low supply voltage. We present a transformer noise-canceling wideband CMOS LNA based on a common-gate topology. The transformer, composed of the input and shunt-peaking inductors, partly cancels the noise origina...

For 5G communication, both sub-6G and millimeter wave bands have their own advantages, while low-noise amplifier (LNA) is an essential component of the first stage receiving system, its performance plays a crucial role in overall system. Therefore, LNAs applicable to ultra-wideband reconfigurable can make full use high low frequency bands, which one research focuses communication development at...

This paper shows the design of a broadband low noise amplifier (LNA) for ultra-wideband (UWB) system on 0.18um CMOS process. The proposed LNA uses resistive shunt feedback technique and an inter-stage inductor as an inductive peaking to realize the flat gain throughout the UWB band. The designed UWB LNA has a noise figure lower than 3.5dB, gain above 20dB in the frequency range 3. 1-10.2GHz. It...
