Abstract:
A cascode low noise amplifier includes an input transistor and an output transistor cascode together, the input transistor has a source coupled to an active inductor, and the output transistor has a drain to provide an output signal. By using the active inductor, the low noise amplifier has smaller size, lower noise figure, and higher gain. The active inductor also provides input impedance matching for the low noise amplifier.
