ABSTRACT:
Aspects of a method and system for a transformer-based high performance cross-coupled low noise amplifier may include one or more circuits that integrate within a single chip, a balun with a low-noise amplifier. A DC current biasing path for the low-noise amplifier may be provided through the integrated balun. The low-noise amplifier may be configured as a cross-coupled low-noise amplifier, where the balun may be directly coupled to the cross-coupled low-noise amplifier. The balun may comprise two or more inductors, wherein one or more of the inductors may provide an electrical path for allowing a DC bias current to flow to ground. Integrating a balun on a single chip with a low-noise amplifier may allow the use of a single received signal input terminal. The biasing voltage may be selected to optimize performance of the low-noise amplifier.
