Abstract
Illustrative impedance matching circuits and methods provide enhanced performance without meaningfully increasing cost or areal requirements. One illustrative integrated circuit embodiment includes: a pin configured to connect to a substrate pad via a solder bump having a parasitic capacitance; an inductor that couples the pin to a transmit or receive circuit; a first electrostatic discharge (ESD) protection device electrically connected to a pin end of the inductor; and a second ESD protection device electrically connected to a circuit end of the inductor, where the first ESD protection device has a first capacitance that sums with the parasitic capacitance to equal a total capacitance coupled to the circuit end of the inductor.
