This article mainly introduces the structure, principle, advantages and disadvantages of MOM, MIM and MOS capacitors and the difference between them. On-Chip Capacitors (MiM, MoM, PiP, Mos Varactor) Catalog Ⅰ MIM capacitor Ⅱ MOM capacitor Ⅲ MOS capacitor Ⅳ Comparison of MIM, MOM, and...
Disadvantages of MIM capacitors: In the 65nm process, even if the upper 9 layers of metal and Poly are used to build MIM, the unit area capacitor is only (1.4fF/micron square). The parasitic capacitor Cp can reach 10% of the total capacitor. MIM circuit Ⅱ MOM capacitor MOM capacitor(M...
What is a Metal-Insulator-Metal (MIM) Capacitor? Metal-insulator-metal (MIM) capacitors are another class of compact capacitors with distinct advantages. They are like a parallel plate capacitor, in which metal plates (electrodes) are separated by an insulating material (dielectric). These capacito...
