Analysis and design of low-distortion CMOS source followers

This paper presents the analysis of CMOS technology based nMOS source follower (NSF), pMOS source follower (PSF), and cascade-complementary source follower(CCSF) using a simplified large-signal model. Three new large-signal second harmonic equations and high-frequency transfer functions are derived....
