Power distribution network design of current-steering, nyquist rate DA converters

Power delivery is the fundamental of all integrated circuit. In most case, the quality of power/ground signal defines the performance or even the function of circuit. Power distribution network varies hierarchically in printed circuit board, package level and on-chip level according to its distribution in space. The complexity of the whole power distribution network restrains its accurate analyze with the corresponding circuit. This paper presents an efficient and accurate methodology which links the on-chip and off-chip designs together. To validate this methodology, a 12 bits 500 MHz current-steering, nyquist rate DA converter is designed. Good agreement between simulation and measurement is achieved by this methodology within an error of ±5%.
