A small-area inductorless configurable wideband LNA with high dynamic range
This paper presents a two-stage fully differential inductorless wideband low noise amplifier (LNA) with high dynamic range, using a switchable capacitive attenuation circuit, selectable-input impedance-matching topology, and bypassable amplifier. The proposed LNA is fabricated in a double-oxide 65 nm / 0.2 ? m minimum channel length CMOS technology and achieves a bandwidth from 500MHz to 2.5GHz, a voltage gain range of 30.6dB, a minimum noise figure of 4.1dB, and a maximum IIP3 of 22.8dBm. The LNA dissipates between 28.8 and 39.5mW and occupies an area of 0.041mm2.
