PHN 13996 16.06.1992, ABSTRACT:, CMOS integrated circuit. An important problem in large integrated circuits is constituted by noise superimposed on the supply. This noise is particularly caused by switching of switching elements such as flipflops, and by heavily loaded output stages. These elements cause current peaks which may give rise to comparatively great fluctuations in the voltage. This problem is solved at least to a great extent in CMOS circuits with standard cells or with custom layout blocks by means of an additional decoupling capacitance in the form of an extra well in the routing channels The decoupling capacitance may be positioned immediately adjacent the switching element …

Why it's free to use
- Filed February 24, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 24, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 24, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
