Abstract
An integrated low noise amplifier includes an on-chip balun, a line impedance matching circuit and an on-chip differential amplifier. The on-chip balun is operably coupled to convert a single ended signal into a differential signal. The line impedance matching circuit is operably coupled to the primary of the on-chip balun to provide impedance matching for a line carrying the single ended signal. The on-chip differential amplifier is operably coupled to amplify the differential signal and is impedance matched to the secondary of the on-chip balun.
