Interdigital Capacitor Equation

interdigital capacitor

As depicted in the fig-1 and equation mentioned below, interdigital capacitor do not require any special steps. It is similar to MIC technology. Capacitance value of this interdigital capacitor depends on W/L ratio, gap distance 'd' between two conductors as well as number of fingers N.

Following equation or formula is used for Interdigital capacitor calculator.
