Abstract:This brief presents an implementation of ultralowpower microcontrollers that use a separate clock network voltage (SCNV) to correct unexpected errors produced by on-chip variations (OCVs). Separating the clock network voltage requires amendments in the standard cell library and physical designs. Here, the experiments used a 65-nm technology that exhibited considerable OCVs, which caused write and retention errors in clocked storage cells and limited the voltage scaling of microcontrollers. Using the SCNV provi… Show more
