Wideband LNA With an Active -C Element

This letter discusses a wideband inductorless low-noise amplifier (LNA) that incorporates a new active -C element, which draws 170 μA of current. A 10 MHz-2.8 GHz proof-of-concept LNA in 65 nm CMOS is proposed. The LNA itself is power- and noise- matched and achieves noise figures as low as 1 dB, voltage gain of 32 dB and IIP3 of - 13.6 dBm.
