We present translational lemmas for the three standard models of parallel computation, and apply them to obtain tight hierarchy results. It is shown that, for arbitrarily small rational constant $$\epsilon > 0$$ , (i) there is a language which can be accepted by a $$U_{\rm E}$$ -uniform circuit family of depth $$c(1+\epsilon)(\log n)^{r_1}$$ and size(More)
This paper presents a structure of millimeter-wave (mmW) on-chip transmission line using redistributed thick copper wires with ground shields. All the layers from standard BEOL layers to the aluminum pad layer can be selected as the ground shield. From electromagnetic field simulations and measurements up to 80 GHz, we prove that global-copper-wire ground(More)
