decap on chip -ieee -patent

Is that true?
When should we ues decap cell in the chip?
 

core decap cells

Having decap cells for designs working at higher freq is essential bcoz, without decap

cells the power delivery network can supply power instantaniously to gates all over

place having high switching bcoz of higher freq.

Hope it helps
 

decap cells

what's the decap cell? can you give an example?
 

Re: Chip will not work above 600MHz without decap cell in co

decap cells r used to reduce noise....and added in betwn cells.....correct me if i am wrong.....

also there are cells called ncap!!!!!!!!
 

decap cell provide capacitance between power and ground, which can smooth the power noise during circuit transition.
