A 1-5-GHz noise-cancelling variable gain amplifier is presented in 0.18--m CMOS technology that achieves a low noise figure (NF) below 4.8-dB over an 11-dB gain range. Its NF is as low as 3.2-dB for the gain range of 5.5 to 11-dB, while its input return loss is better than 13-dB over the entire gain range of -5 to 11-dB. The measured input-referred two-tone third-order intercept point (IIP3) at 2...
In addition to LNA (low noise amplifier) noise figure, gain and input matching, its linearity is also an important consideration. An LNA must amplify signal without adding too much noise but also remain linear even when strong signals are received. In the narrowband LNA topology, good values of S-parameters and noise performance are achieved at the expense of linearity. In order to improve LNA linearity,...
An ultra-wideband (UWB) low noise amplifier (LNA) that consists of two cascode and shunt feedback stages is presented. Measurement results show the maximum power gain (S21) of 11.9 dB with the 3-dB band from 2 to 6.5 GHz and input/output reflection coefficient (S11 , S22) of less than -7.8 dB from 2 to 11 GHz. In addition, the fabricated LNA achieves the average noise figure (NF) of 4.5 dB from 2...
The design and measured performance of two low-noise amplifiers at 15 GHz and 20 GHz realized in a 90 nm RF-CMOS process are presented in this work. The 15 GHz LNA achieves a power gain of 12.9 dB, a noise figure of 2.0 dB and an input referred third-order intercept point (IIP3) of -2.3 dBm. The 20 GHz LNA has a power gain of 8.6 dB, a noise figure of 3.0 dB and an IIP3 of 5.6 dBm. Compared to previously...
