Abstract	A wideband single-ended input, differential output balun-LNA is proposed for multi-standard wireless applications between 10 MHz and 3 GHz. The common-gate (CG) input stage in combination with a noise cancellation topology is adopted for wideband input matching and low-noise figure. An output stage with g m ″ compensation technique is utilised to promote the limited gain of the CG input stage, and obtain an optimised linearity performance. Realised in TSMC 180 nm RF CMOS process, the LNA provides a gain of 19.7 dB, a maximum input third-order interception point of 1.13 dBm, and a minimum NF AQ1 of 1.93 dB over a 3 dB bandwidth from 10 MHz to 1.7 GHz. Meanwhile, the proposed LNA shows good measured performance over the frequency band of 1.7–3 GHz.
