Generator scheme and circuit for overcoming resistive voltage drop on power supply circuits on chips

Apparatus is used to dynamically control the power output of generators (16A-16H) of a generator system on a chip (10) to load circuits on the chip. A power bus (14) is directed along at least one ""spine"" section (18) on the chip which may intersect with at least one ""arm"" section (19) on the chip for supplying power from the generators, which are coupled to the power bus in the ""spine"" section thereof, to the load circuits on the chip. The power bus has a feedback lead (32) from each end which is remote from the generators for providing a continuous measurement of a voltage drop occurring at each remote end. At least one detector circuit (100) is located at a predetermined point adjacent the generators of the chip for comparing a voltage from the generators measured at the predetermined point with the concurrent voltage drop measured at an associated remote end. In response to such comparison, the at least one detector circuit generates control signals (BOOST and SPEED) for transmission to the generators for altering a generated voltage to maintain a predetermined power level on the power bus in response to load changes caused by the circuits on the chip.
