    Divide-by-1 clock divider through D flip-flops

    Is there a way we can achieve divide-by-1 clock through D flip-flop or transmit the clock pulse to Q?

    what are you looking to gain from a divide by 1?

    Hi,

    Divide by one means "no operation at all"
    Output = input
    Useless function

    For such a useless function you may use a
    * buffer
    * AND gate (both inputs tied together)
    * OR gate (both inputs tied together)
    ... or several other non clocked solutions.

    But not with a "clocked" solution like a DFF.
    The problem is that a DFF can react on one clock edge only (either rising or falling).... thus it can not react on the other edge.
    But for a "divide by one" you need to react on both incoming edges. Impossible.
