Abstract
A low-noise amplifier, that utilizes multiple monolithic transformer magnetic feedback to simultaneously neutralize the gate-drain overlap capacitance of the amplifying transistor and achieve high gain at high frequencies when driving an on-chip capacitance, is shown. The multiple transformer topology permits negative and positive feedback to be applied constructively, allowing for a stable design with adequate gain and large reverse isolation without Noise Figure degradation.
