Use a latch, and AND gate to generate gated-clock. This gated-clock can be free from glitch.

I agree that An AND gate with a negative Latch is the most popular circuit available. However, you need to pay attention when you do STA. Also, you need to watch out how many flops each clock gating circuit could drive 1--> 8 or 1--> 16.
