ABSTRACT:
Embodiments of the present invention include circuits for use in wireless receivers that provide wide band matching with improved gain and noise performance. In one embodiment, the present invention includes a wireless receiver comprising an antenna, a first transistor having a source coupled to the antenna, a second transistor having a gate coupled to the antenna and a network comprising a first terminal coupled to the antenna, a second terminal coupled to the source of the first transistor and a third terminal coupled to the gate of the second transistor, wherein the network has a transimpedance between the second and third terminals so that noise generated by the first transistor is differentially rejected by the system across a predetermined range of frequencies.
