PIPELINE CIRCUIT

摘要

There is provided an electronic circuit that is harder to crack using power analysis techniques, the electronic circuit comprising first and second pipeline stages and a latch positioned between the pipeline stages; wherein the electronic circuit is adapted to operate in a normal mode in which the latch is opened and closed in response to an enable signal, and a reduced mode in which the latch is held open to reduce a current peak associated with the opening and closing of the latch. ® KIPO & WIPO 2007
