BROADBAND MULTI-STAGE AMPLIFIER WHICH USES A DIFFERENT PEAK POINT, CAPABLE OF IMPROVING A GAIN AND A BAND PROPERTY BY THE CROSS OVERLAPPING OF THE AMPLIFIER BAND OF EACH STAGE

摘要

PURPOSE: A broadband multi-stage amplifier is provided to improve a gain by fundamentally secluding the generation of loss due to a separate parallel resistor.;CONSTITUTION: A broadband multi-stage amplifier is composed of the inductor peak point mode amplifiers of a plurality of stages. The amplifier of each stage resonates in the peak frequency dispersed in a vertical direction based on the center frequency of a preset usage band. The Q value of the amplifier of each stage is determined by the internal resistance of an inductor. At least one between the amplifier size of each stage and the inductor size is different according to a stage.;COPYRIGHT KIPO 2011
