A New Approach to the Design of CMOS Inductorless Common-gate Low-noise Amplifiers

This work proposes a new approach to design a simple and effective LNA reaching very competitive results in 1.2V 65-nm standard CMOS technology. The proposed design uses a transconductance enhancement technique to achieve 2.3 dB of noise figure at the 5 GHz band. The paper exposes the advantages of a reduced number of devices in the circuit and analyses the topology. Simulations with complete technology models and statistical analysis are presented for more precise results.
