Abstract: An area efficient distributed device for integrated voltage regulators comprising at least one filler cell coupled between a pair of PADS on I/O rail of a chip and at least one additional filler cell having small size replica of said device is coupled to said I/O rails for distributing replicas of said device on the periphery of said chip. The device is coupled as small size replica on the lower portion of said second filler cell for distributing said device on the periphery of said chip and providing maximal area utilization.

Abstract: In a method for recovery of a dock from a received digital data stream and an apparatus for recovering a clock from a received digital data stream, phase-shifted dock signals are generated from a receiver's dock. After selecting one of the phase-shifted clock signals, two other phase-shifted clock signals are determined. Depending on sample values taken at rising/falling edges of the three selected phase-shifted clock signals, counter values are increased and compared. The selection of phase-shifted clock signals and the steps of sampling the input digital data stream, comparing the values and increasing counter values, if required, are repeatedly performed until the comparison result of the counter values indicates that one of the latter determined phase-shifted clock signals strobes the received digital data stream in the centre of a bit period.

Abstract: A static random access memory (SRAM) device includes a memory array of a plurality of memory cells, a controller that receives an external clock signal formed by a succession of external pulses and generates an internal clock signal formed by a succession of internal pulses, and a driving circuit that receives the internal clock signal. The controller is operable in a first mode, wherein the controller generates, for each external pulse, a corresponding internal pulse and the controller controls the driving circuit so that the driving circuitry carries out one access to the memory array for each internal pulse. The controller is further operable in a second mode, wherein the controller generates, for each external pulse, a pair of internal pulses, and the controller controls the driving circuitry so that, for each pair of internal pulses, the driving circuitry writes a first data item in a set of memory cells, and then reads the set of memory cells, so as to acquire a second data item.

Abstract: A method for transmitting data on a configurable bus of z physical links, including receiving input data on an input bus at at least one of a plurality of data rates, selecting a number of physical links n, amongst the z physical links, on which data is to be transmitted, selecting a clock frequency f at which the data is to be transmitted on the configurable bus, wherein the selections of n and f are based on information concerning the at least one of the plurality of data rates, the number of links used on the input bus.
