Abstract
We present a wideband resistive feedback CMOS low-noise amplifier (LNA) with noise cancellation technique for ultra-wideband applications. The LNA achieves a 3-dB bandwidth of 0.7-6.5 GHz, power gain of 12.5 dB, and noise figure of 3.5-4.2 dB within the 3-dB bandwidth. The input matching is better than -11 dB from 0.7 to 12 GHz. The IIP3 is measured -5 dBm at 5 GHz. It is implemented in a 0.18 mum standard digital CMOS technology, occupies an area of 0.78 mmtimes0.68 mm, and consumes 11.1 mW from a 1.8 V supply.
