LOW-POWER MULTI-OUTPUT LOCAL CLOCK BUFFER

摘要

An improved circuit for reducing a capacitance load on a processor. The circuit includes a global clock circuit capable of producing a primary timing signal. The circuit further includes a local clock buffer circuit having a plurality of outputs. The local clock buffer circuit is connected to the global clock circuit. The local clock buffer circuit is capable of producing a secondary timing signal based on the primary timing signal. The circuit also includes a latch connected to the local clock buffer circuit. The latch is capable of producing a select signal that controls which outputs of the plurality of outputs are active. Only a third signal, based on the secondary timing signal, controls an operation of the latch.
