DESIGN FOR SPEED

Hi,  this post is for the designing of high speed digital design . some concepts of fast current in wires and how to control that fast current for fast processing .
        CMOS technology is used in  the ic. because of many reasons like - less area , easy to fabriacate , low power consumption , fast speed , balanced circuits .

       there are many techniques for speed up  in design in data path and clock paths.
some are -

• put the buffer in critical path . buffer insertion will give many effect in path . it will increase the speed , change the slope of transation of voltage , will give the full swing , decrease the cross cap . 
•   inside the gate put the input (which have the probability of coming late ) near to output .so critical path will be less .
• put domino logic .
• increase the supply voltage where ever is high speed require . for this multivoltage cell are used .
• put the transistor near to the output that have probability of input coming late .
• no of level in a path should be according to the logical effort .

there are many more .............
