Abstract
A power-efficient neutralized signal amplifier for use in ultra-low power narrowband receiver applications. A neutralized signal amplifier having: an impedance transformation element coupled to an amplifier input and having a differential output; a gain cell, having a differential input and a differential output, the differential input coupled to the differential output of the impedance transformation element and the differential output coupled to the amplifier output; and a neutralization element coupled to the gain cell differential output and cross-coupled to the differential output of the impedance transformation element, where the coupling of the neutralization element to the differential output of the impedance transformation element provides that the input impedance of the neutralized signal amplifier is substantially determined by reflected resistive parasitics of the impedance transformation element.
