【 摘 要 】

References(8)Cited-By(1)An improved figure-of-merit (FoM) equation is proposed for op-amp evaluation. This equation has a modification factor to include the effect of the phase margin, which is not considered in a conventional FoM equation. Simulation results confirm that the proposed FoM equation drastically suppresses the effect of load capacitance variations. By using the proposed FoM equation, evaluations of op-amps become more reasonable as compared with the comparisons using the conventional FoM equation.
