  • Abstract
    In this paper, results are presented for a Barium Strontium Titanate (BST) interdigital capacitor (IDC) which is designed and simulated to analyze the effect of variations in its geometry on the shape of the nonlinear capacitance - voltage (C-V) curve. From this analysis, the narrow, broad and intermediate C-V curves are determined. The broad curve could withstand input power of up to 41 dBm compared to 32 dBm and 29 dBm for the intermediate and narrow curves respectively. The tunabilities of the broad, itermediate, and narrow curves are 28%, 54%, and 73% respectively.
