Abstract
An inductor-less balun low-noise amplifier (LNA) includes a cross-coupled network coupled between first and second input terminals and first and second summing nodes. The cross-coupled network may include: a first non-inverting gain stage coupled between the first input terminal and the first summing node; a first inverting gain stage coupled between the first input terminal and the second summing node; a second non-inverting gain stage coupled between the second input terminal and the second summing node; and a second inverting gain stage coupled between the second input terminal and the first summing node. The cross coupled network may be configurable to provide common-mode rejection when operated in a differential or in a single-ended mode of operation.
