In this paper, noise-shaping gain-fi which minimize noise over the range of pas been studied. These techniques will be applying it on a part of CMOS mobile-TV re mainly focuses on designing a low pass filter, cascaded parts. The first part is Frequency De Resistance (FDNR) based third-order noise section, which has DC gain of 80dB , with cu 818KHz and input referred noise voltage pow of 5.2nV/sqrt(Hz). The second part is Asy Frequency Dependent Negative Resistance feedback network, which is a part of instrume It has DC gain of 20dB, with cutoff frequenc input referred noise voltage power spe 83nV/sqrt(Hz). These two filters depend on which has DC gain of 82dB, with unity g 319MHz, phase margin of 61° and power diss This CMOS op amp is designed based on technology with power supply of ±1.5V.
