Abstract :
This paper presents the performance of scalable polynomial equation for very wide range of metal-insulator-metal (MIM) capacitor value which is obtained through curve fitting or optimization technique. It is used to describe the behavior of lumped element circuit model that has the same characteristic as the measurement data. The scalable polynomial equation is developed based on lumped element circuit model for frequency range of 0.8 GHz up to 18 GHz. Finally, 4 different scalable polynomial equations are derived, and applied in 2.4 GHz LNA circuit design for model verification.
