hi,
load line means load device characteristics,lets take common source amplifiers,in that resister character sics are load line.Where as in inverter(cmos inverter),if u assume nmos as amplifing device,then pmos is load and pmos characteristics are load curve,where as for opposite assumption nmos characteristics are load curve.I hope u understand.
