Metal-Insulator-Metal (MIM) Capacitor
The C_MIM module represents a series metal-insulator-metal capacitor (MIM-Capacitor) in coplanar line technique. The width of capacitor and its distance to the ground are given in a line type addressed by C_LTYPC. The total length of the capacitor is given by L. The dimensions of connected lines at ports are defined using data items addressed by C_ LTYP1 and C_LTYP2.
|Parameter||Description||Range of Usage|
|L||Total length of the capacitor|
|C_LTYPC||ID of coplanar transmission line applied at capacitive section|
|C_LTYP1||ID of coplanar transmission line applied at ports 1|
|C_LTYP2||ID of coplanar transmission line applied at ports 2|
|DIE_IDX||Index to dielectric layer definition for capacitors in currently selected foundry|
|C_SUB||ID of coplanar substrate definition|
|C_GRID||ID of simulation control data|
|TEMP||ID of element temperature definition used for noise computation|
|L1min= max( W1+2S1+2GW1, W2+2S2+2GW2, WC+2SC+2GWC)|
For the modeling of C_MIM element, the capacitive region is calculated as two coupled coplanar lines (see Analysis of Multiple Coupled Coplanar Lines). The matrices of distributed parameters (capacitance per unit length, inductance per unit length, etc.) are determined using quasi-static FD-calculations.
