Abstract
A tuneable buffer circuit for use in a clock tree has multiple buffers in parallel, each buffer having a grounding function, and also a bypass switch in parallel with the buffers. The circuit has a normal mode of one buffer connected into circuit, a first low voltage mode of multiple buffers connected into circuit in parallel without grounding function, a second low voltage mode of the buffers connected into circuit in parallel with grounding function and a bypass mode.
