Abstract
Power distribution system noise affects computer product timing performance, signal integrity and electromagnetic interference. Between 1 MHz and 1 GHz, the primary means of reducing power distribution noise is with ceramic decoupling capacitors. To achieve a certain target impedance, it is important to characterize the ESR of ceramic decoupling capacitors, as this directly determines the number of capacitors required on a board. A new technique to extract ESR is described in this paper. Another factor which determines the capacitance value of decoupling capacitors is the ESL (equivalent series inductance) associated with capacitors mounted on a PCB. A study that compares the ESL of different pad layout geometries is also presented.Keywords
