Abstract
Official abstract text for this publication.
A device includes a low noise amplifier (LNA) for amplifying an input signal, with the LNA including a first transistor configured to receive the input signal, a second transistor configured to receive a bias current and forming a current mirror for the first transistor, and an operational amplifier (op amp) operative to generate a bias voltage for the first and second transistors to match operating points of the first and second transistors.
