Input/output termination for ripple prevention

摘要

Aspects of this disclosure relate to a termination circuit configured to mitigate crosstalk from a radio frequency (RF) input/output (I/O) path to a second I/O path, such as a digital I/O path. Such crosstalk can be due to coupling between adjacent bond wires, for example. The termination circuit can include a low impedance loss path, such as a series RC shunt circuit. According to certain embodiments, an electrostatic discharge (ESD) protection circuit can be in parallel with the termination circuit.

主权项

1. An electronic device comprising:
a die comprising a radio frequency (RF) input/output path electrically connected to a first bond pad of the die and a second input/output path electrically connected to a second bond pad of the die, the RF input/output path configured to process an RF signal, and the second I/O path configured to process a second signal, the second signal being a non-RF signal; a first bond wire electrically connected to the first bond pad of the die; and a second bond wire electrically connected to the second bond pad of the die; and a termination circuit electrically connected to the second bond pad of the die, the termination circuit configured to mitigate against effects of crosstalk due to coupling between the first bond wire and the second bond wire by providing a load for the second I/O path such that the second I/O path is dampened.
