ABSTRACT:
An embodiment of the present invention is a low noise amplifier using differential inductors. An input matching circuit having first and second differential inductors matches an input resistance at an input having input terminals. A differential amplifier circuit converts the input voltage a current. An output circuit provides an output voltage buffer with a low output impedance at an output having output terminals. A cascode circuit increases isolation between the input and the output terminals.
