High dynamic range low-power differential input stage

A low-power high dynamic range RF input stage with a noiseless degeneration component, such as a capacitor, is provided. High dynamic range means a combination of low noise contribution by the stage and a low level of intermodulation products occurring especially at high input levels. Low power means that the power consumption of a conventional input stage is about 5 times higher than the power consumption of the stage according to the invention, for the same noise, gain and distortion level. This new stage can be used in amplifiers, but also in the lower stage of double balanced mixers (-) commonly used in RF receivers, examples of which are applications, are provided.
