Abstract

A cascode SSTL output buffer using a source follower circuit includes a biasing circuit arranged to generate a first bias signal. The source follower circuit is responsive to the first bias signal and generates a second bias signal which is then used by a cascode circuit that receives an input signal to the SSTL output buffer to drive an output signal from the SSTL output buffer.
