Design of Interdigitated Capacitors and Their Application to Gallium Arsenide Monolithic Filters

CAD modeling of coplanar waveguide interdigital capacitor

“…Although Tables III and IV show some variation between our results and those available in the literature, the other comparisons (presented below) give us more confidence in our results. It is believed that the experimental results in [5,6] are not very accurate, since they rely upon wire bonds and resonance measurement, not upon the direct measurement of the component with modern de-embedding techniques. Moreover, it should be noted that a microstrip IDC was considered in [5,6] and the effect of the terminal strips of the IDC was included in the measurements and the analysis.…”

“…Capacitance C s is the most important element in the circuit, and has been the subject of study in many papers [3][4][5][6][7]. Recently, using conformal mapping, Gevorgian [10] presented a closed-form expression for the C s of a multilayered substrate IDC.…”

Capacitive Interdigital Sensor With Inhomogeneous Nematic Liquid Crystal Film

“…Interdigital capacitors (IDC) have been involved in many sensing applications over the past five decades [1][2][3][4][5][6][7][8][9][10]. Properties of the IDC have been studied by many authors and have shown high performance when being used as sensors involved with many scientific applications.…”
