Abstract

A new topology of transformer based low noise amplifier is presented. The structure realizes a low noise input match and a current gain greater than one by a current to current positive feedback closed around a common gate stage. The amplifier is inserted in a high linearity current mode RF front-end receiver working between 4.15-4.4GHz with a NF of 4.2dB, a gain of 24.2dB and an IIP3 of -2dBm
