Patent abstract
A dual feedback low noise amplifier includes a negative-feedback capacitive mutual-coupled common-gate amplifier of parallel-input parallel-output (PIPO) composed of a first transistor, a second transistor, a first coupling capacitor and a second coupling capacitor and a positive-feedback common-gate amplifier of parallel-input parallel-output (PIPO) composed of the first transistor, the second transistor, a first transformer and a second transformer. By means of dual feedback, the transconductance gain of the dual feedback low noise amplifier is increased, and the noise figure of the dual feedback low noise amplifier is decreased.
