Summary:A dual feedback low-noise amplifier include a shunt-shunt negative feedback common gate amplifier composed of a first transistor, a second transistor, a first couple capacitor and a second couple capacitor, and a shunt-shunt positive feedback common gate amplifier composed of the first transistor, second transistor, a first transformer and a second transformer. Using the dual feedback to increase the gm and reduce the noise figure of the dual feedback low-noise amplifier.
