US Patent 12095424 Miniature ultra-low-power LNA employing current reuse and bias sharing

A low noise amplifier (LNA) offering one or more of the following benefits: increased gain, reduced power consumption, and/or reduced area, while achieving a similar noise figure, is disclosed. The LNA achieves these benefits by employing an inductorless chip design, current reuse among the transistors, bias sharing, limited AC coupling capacitors, common gate input device feedback, and careful sizing of the transistors.
