WebFigure 5b shows that, for low source resistance, the E O of the CMOS amplifier, like that of the bipolar amplifier, converges with the amplifier’s intrinsic voltage-noise density (e N). The difference between the bipolar and the CMOS amplifier lies where the noise density converges for high source resistance. As already noted, the bipolar ampli- Webdiode-connected NMOS with source degen-eration.
