This brief presents a bandwidth and gain enhancement technique for packaged single-ended wideband low noise amplifier (LNA) module for high-sensitivity receivers. Wide bandwidth, low noise figure (NF), and high power gain are achieved by using gate-source inductors assisted impedance matching, current reuse feed-forward noise cancellation technique, and integrated shunt peaking output buffer. Fabricated in UMC 65-nm CMOS technology, the proposed LNA packaged in quad-flat no-leads package module achieves a maximum power gain of 20.5 dB, NF of 2-2.5 dB, 3-dB bandwidth from 0.4 to 2.2 GHz, and third-order inter modulation intercept the point of -5 dBm while consuming 25 mA current (including buffer) from 1.2 V supply. © 2004-2012 IEEE.
