Interdigital capacitor calculator
This page of converters and calculators section covers Interdigital capacitor calculator.
EXAMPLE#1:
INPUTS:
Dielectric constant = 9.8 , Number of fingers=10, finger length = 0.0025 cm ,
finger width = 0.05 cm
OUTPUT:
Capacitance = 0.4 pF/cm
EXAMPLE#2:
INPUTS:
Dielectric constant = 13 , Number of fingers=10,
finger length = 0.001 inch = 0.001*2.54 cm
finger base width = 0.02 inch = 0.02*2.54 cm
OUTPUT:
Capacitance = 0.51 pF/cm
Interdigital Capacitor Equation
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.
