This paper presents a simple and accurate nonlinear four-terminal floating
nullor (FTFN) macromodel. The FTFN characteristics are simulated by using t
he new macromodel and are compared with the simulation results obtained by
SPICE device models. The results show that the proposed FTFN macromodel rep
resents the CMOS FTFN with approximately the same accuracy as semiconductor
SPICE device models but with a significantly reduced computer time.
