PROBLEM TO BE SOLVED: To provide a neutralization technique for differential low noise amplifiers (LNAs). SOLUTION: A differential LNA has first and second input MOS transistors (MT, MC), with differential inputs applied to their respective control gates and differential outputs taken at their respective drains. A gate-to-drain, Cgd, feedback capacitances of the first and second input MOS transistors are neutralized by respective gate-to-source, Cgs, capacitances in the two neutralizing MOS transistors (MN1, MN2).
