Abstract

In this paper, a new gain enhancement technique which is recommended for folded cascode LNA structures at low voltage and low power applications is presented. In order to increase power gain, a new modified version of gm-boosting technique is employed which increases the power gain while consuming no extra power. The new topology shares its DC current at the folded stage in order to reduce power dissipation associated with the gm-boosting technique. The proposed technique reduces power dissipation almost 27%, additionally; other parameters such as power gain and noise figure have been slightly improved. In the proposed LNA, power gain and noise figure are15dB and 3.2dB respectively. It consumes 1.3mW under 0.6 supply voltage.
