Method and system for a single-ended input low noise amplifier with differential output

A system for processing signals, the system comprising:

• one or more circuits in a wireless receiver, said one or more circuits comprising a low noise amplifier (LNA) and a balun, wherein said one or more circuits comprise CMOS transistors within said LNA, wherein said one or more circuits comprise configurable gate-source capacitors, and wherein said one or more circuits are enabled to:
• configure said LNA for single-ended input mode or differential input mode;
• configure said balun to operate in said single-ended input mode or said differential input mode, wherein said balun functions as a load for said LNA;
• and
• tune a transition frequency of said LNA via said configurable gate-source capacitors coupled to said CMOS transistors,
• wherein said one or more circuits comprise switches outside of a signal path to said LNA, and said one or more circuits are operable to configure said LNA for said single-ended input mode or said differential input mode via said switches outside of said signal path to said LNA.

A system, comprising:

• a low noise amplifier (LNA) on a chip;
• switches for configuring said low noise amplifier (LNA) for single-ended input mode or differential input mode, wherein said switches are outside of a signal path to said LNA;
• a balun within the chip configured to provide a load for said LNA;
• and
• gate-source capacitors configured to provide a tunable matching network gain and tunable impedance matching of said LNA via a programmable transition frequency of said LNA.
