Abstract
A capacitive coupling isolation device and a receiving circuit are provided. The capacitive coupling isolation device includes an external coupling capacitor and the receiving circuit. The external coupling capacitor is electrically connected to a transmitting circuit and the receiving circuit. The receiving circuit includes a protection circuit architecture, which includes an input bonding pad structure and a filter resistor. The input bonding pad structure is formed by alternatively disposing patterned metal layers and dielectric layers, and the input bonding pad structure includes a pad capacitor and a filter capacitor. The pad capacitor is electrically connected to the external coupling capacitor and a filter capacitor. The filter capacitor and the filter resistor are both electrically connected to the pad capacitor and a ground end. The filter capacitor and filter resistor form a low-pass filter. The external coupling capacitor is a built-in package capacitor.
