Abstract
A circuit for electrostatic discharge (ESD) protection for wide frequency range multi-band interfaces. The interface may be split into a plurality of signal paths. Each signal path may include an ESD protection circuit configured to shunt an ESD current on each signal path to either ground or supply voltage and a filter configured to block signals from other signal paths. The signal paths are connected to a common signal line such that the signals for the plurality of signal paths can be transported simultaneously. The plurality of signal paths may be a high frequency path and a low frequency path. The low frequency path may include an inductor connected in series and the high frequency path may include a capacitor or transformer connected in series. The ESD protection circuit on each signal path is placed behind the inductor, the capacitor or the transformer.
