Abstract:
1. A low-noise amplifier (LNA) comprising: a first input terminal for receiving a first portion of an input signal, the first input terminal adapted to be DC coupled to a first supply terminal; a second input terminal for receiving a second portion of the input signal, the second terminal adapted to be DC coupled to a second power supply terminal; an output terminal; a first transistor comprising a source coupled to the first input terminal, a gate configured to receive a first direct current (DC) bias signal, a drain coupled to the output terminal; and a second transistor comprising a source coupled to the second input terminal, a gate configured to receive a second DC bias signal, a drain coupled to the output terminal, and wherein the LNA is configured to use source degeneration of the first and second transistors to reduce sensitivity to turn on voltage variations across process corners.
