Working Principle

The capacitance of an interdigitated capacitor is determined by the number of fingers, the width of each finger, the spacing between fingers, and the dielectric constant of the material between the fingers. The formula used is:

C = ε * (N * w) / s

Where:

  • C = Capacitance (F)
  • ε = Dielectric Constant
  • N = Number of Fingers
  • w = Finger Width (m)
  • s = Finger Spacing (m)
