Abstract:
A receiver front end having low noise amplifiers (LNAs) with enhanced input third order intercept point is disclosed herein. A cascode having a “common source” configured input FET and a “common gate” configured load FET have a degeneration circuit comprising a tank circuit tuned to a harmonic of the operating frequency.

Claim (Index 16):
A method for fabricating a front end amplifier, comprising:\n (a) determining a system impedance and an operating frequency; (b) determining operational characteristics of an input FET, comprising at least an impedance from gate to source of the input FET when operating as an amplifier within the front end amplifier at the operating frequency; (c) determining a total impedance required for an input impedance matching circuit and a degeneration circuit at the operating frequency, such that the series combination of: (i) the impedance from gate to source of the input FET, (ii) the impedance of the input impedance matching circuit and (iii) the impedance of the degeneration circuit are equal to the system impedance at the operating frequency: (d) determining a ratio of impedance between the input impedance matching circuit and the degeneration circuit at the operating frequency; (e) based on the ratio, determining a value for the impedance of the degeneration circuit at the operating frequency; and (f) determining values of capacitance and inductance for elements of a tank circuit within the degeneration circuit such that the tank circuit in the degeneration circuit is near resonance at a first frequency, the first frequency being a harmonic of the operating frequency and such that the tank circuit provides the determined value for the impedance of the degeneration circuit at the operating frequency.
