Abstract
The low noise amplifier (LNA) of the present invention comprises an input stage including an input inductor and an input circuit portion. The input circuit portion is operably connected to the input inductor and includes an input gain portion. The LNA further comprises an output stage that is operably connected to the input stage. The output stage includes an output inductor and an output circuit portion. The output circuit portion is operably connected to the output inductor and includes an output gain portion. The input and output inductors are distinct, off-chip components. However, the input circuit portion and output circuit portion are fabricated on a single, integrated circuit chip with CMOS technology. The input stage includes an input impedance that is matched to a system impedance while the output stage includes an output impedance that is matched to a system impedance.
