Hello,

I have a question: what is a clock period delay and how is it implemented in a integrated circuit? I am new to designing I.C.'s and would like to know how it's implemented. Any help is appreciated. Thanks

Jason

Are you designing IC's? You surely don't do this on your own. Normally, your employer has the required documentation.

A clock period delay is implemented with delay-lines. Usually an RC circuit - which can be on the chip itself, but it can also be external (a real physical wire of a specific length will do the job too). You need a lot of mathematical skills to design this.

Clock period delays are needed to keep all logic elements synchronized. As the slowest circuits cannot be accelerated, the fastests are slowed down - with delays.
