  • Low-noise amplifier with high linearity
    Patent number: 8803612
    Abstract: A low-noise amplifier with high linearity has two common source FET amplifying stages, where the amplifier performance is linearized by use of a second stage active biasing circuit including a current mirror with a feedback network. The linearity improvement technique is employed on a 0.5-2 GHz flat gain amplifier. The improvement causes nodegradation to other RF parameters and allows for the amplifier circuit to be realized in a gallium arsenide microwave monolithic integrated circuit.
