ABSTRACT
Because of its nature, the approach to an on-chip power distribution network (PDN) is quite different from that of an off-chip PDN. In this chapter, on-chip PDN modeling is discussed. We begin Section 5.2 by modeling on-chip capacitors. Section 5.3 extracts the electrical characteristics of the on-chip wires forming the PDN. Section 5.4 is devoted to an off-chip PDN incorporating PCB and vias. Section 5.5 investigates the power supply induced jitter. The signal output is contaminated by the supply voltage fluctuation; the trends are analyzed at the transistor level and physically understood.
