Abstract
Low noise amplifiers (LNAs) are provided, the LNAs comprising: a common gate matching network; a capacitord; a resistord; a coild, wherein a side1 of coild is coupled to a side1 of capacitord, a side1 of resistord, and a V+ and a side2 of the coild is coupled to a side2 of capacitord, a side2 of resistord, and a network input; a capacitors; a resistors; a coils, wherein a side1 of coils is coupled to an LNA input, a side1 of capacitors, a side1 of resistors, and a network output and a side2 of coils is coupled to a side2 of the capacitors, a side2 of resistors, and ground; and an output coil that is magnetically coupled to coild and coils and having a side1 coupled to a first terminal of an LNA output and a side2 coupled to a second terminal of the LNA output.
