摘要

传统CMOS技术缺乏像双极技术那样简单的开环缓冲器。简单的源-从动器缓冲器受到驱动器件的信道长度调制作为谐波失真的主要来源。在本文中，我们提出了一种新的源跟随器缓冲器，它的驱动设备是级联编码的。因此，与传统电路相比，该电路可改善谐波失真达20 dB。

A highly linear cascode-driver CMOS source-follower buffer

Traditionally CMOS technology lacks a simple open-loop buffer like emitter-follower of bipolar technology. The simple source-follower buffer suffers from channel-length modulation of the driver device as the main source of harmonic distortion. In this article we present a novel source-follower buffer that its driver device is cascoded. Thus, the circuit can improve harmonic distortion up to 20 dB relative to conventional one.
