Abstract
An integrated circuit suitable for use at high frequencies and comprising a first capacitor having an input and an output, as well as a ground connection, wherein the capacitor is ESD-protected through an resistor between the capacitor output and the ground connection, which resistor has a resistance value that is sufficiently high so as to prevent any substantial influence on RF performance of the ground connection.
Claims19
An integrated comprising:
- a capacitor having
- an input node;
- and
- an output node connected to an external ground node that is outside of the integrated circuit;
- an internal ground node;
- and
- an ESD-protection resistive component that is connected between the capacitor output node and the internal ground node and that has a resistance value that is sufficiently high to avoid substantial RF coupling, for frequencies up to at least 3.0 GHz, between the internal ground node and the external ground node.

An integrated circuit arrangement comprising:
- an integrated circuit located on the integrated circuit carrier including
- a substrate;
- an internal ground node located below the substrate;
- a capacitor located above a bottom surface of the substrate and having an output node and an input node;
- and
- a resistive element providing electrostatic discharge (ESD) protection for the capacitor by providing a first current path from the output node of the capacitor to the internal ground node;
- and
- an impedance element providing a second current path from the output node of the capacitor to the external ground, wherein the ratio of resistances between the first current path and the second current path is sufficient to substantially decouple the external ground node from the internal ground node at circuit-operating frequencies of at least 0.9 GHz.
