Performance Regions CK Cheng CSE Dept. UCSD
Spectral Content (0,fknee) • fknee = 0.5/tr Hz • fedge= 0.35/tr Hz • tr= T bit width
Lumped-Element Region • H(w,t)=e-gamma(w)z+jwt • For lumped-element region |length gamma(w)|< delta, delta:1/4
LC Region: Char. Impedance • Zc=[(jwL+RDC)/jwC]1/2 • =(L/C)1/2(1+RDC/jwL)1/2 • =Z0(1+1/jwT), T= 2L/RDC
LC Region: Char. Impedance • Zc=(R+sL/sC)1/2=Z0(1+1/sT), T=2L/R • sL>>R • Zc(t)=Z0(1+t/T) • t<<T
