Abstract

Traditionally, input source follower buffers for analog-to-digital converters (ADCs) lacked sufficiently high linearity. This was due in part to source follower buffers having to drive external capacitive loads by generally providing a signal current to the capacitive load. Here, a buffer is provided that includes a source follower buffer and other biasing circuitry (which provided the signal current). Thus, the overall linearity of the input circuitry (namely, the input buffer) is improved.
