A 14:1 dynamic MUX FF with select activity detection

A 14:1 dynamic MUX FF is discussed. The design uses 2 cascaded dynamic stages to investigate the 14:1 MUX with a dynamic FF. In addition, replication is used to maintain latch state when all selects are inactive. The timing of the MUX FF is evaluated with a proposed slew detector. Fabricated in a 90nm CMOS process, the chip has a 2X speed increase and 70% area reduction compared to conventional methods
