Abstract
A chip is provided in which an on-chip matching network has a first terminal conductively connected to a bond pad of the chip and a second terminal conductively connected to a common node on the chip. A wiring trace connects the on-chip matching network to a circuit of the chip. The on-chip matching network includes an electrostatic discharge protection (ESD) circuit having at least one diode having a first terminal conductively connected to the bond pad and a second terminal connected in an overvoltage discharge path to a source of fixed potential. The matching network further includes a first inductor coupled to provide a first inductive path between the bond pad and the wiring trace, a termination resistor having a first terminal connected to the common node, and a second inductor coupled to provide a second inductive path between the wiring trace and a second terminal of the termination resistor.
