Abstract :
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
