Claim 15:
16. A system, comprising:
an ablation device including a set of electrodes disposable near cardiac tissue of a heart;
a signal generator configured to generate a pulse waveform, the signal generator coupled to the set of electrodes and configured to repeatedly deliver the pulse waveform to the set of electrodes, the set of electrodes, in response to each delivery of the pulse waveform, configured to generate a pulsed electric field to ablate the cardiac tissue and to induce voltages and currents in a set of sensors disposed near the ablation device;
a protection circuit configured to selectively couple and decouple an electronic device to and from the set of the sensors while the signal generator remains coupled to the set of electrodes, the protection circuit configured to transition between a closed-circuit configuration in which the set of sensors are coupled to the electronic device and an open-circuit configuration in which the set of sensors are decoupled from the electronic device, the protection circuit comprising a first set of switches and a second set of switches; and
a processor coupled to the protection circuit, the processor configured to control the protection circuit to:
during a first time interval, cause the first set of switches to transition from a conducting state in which the set of sensors is coupled to the electronic device to a non-conducting state in which the set of sensors is decoupled from the electronic device; and
during a second time interval that begins before and ends after the first time interval, cause the second set of switches to couple a set of channels associated with the set of sensors to a common node,

wherein the first and second time intervals begin before and end after each delivery of the pulse waveform to the set of electrodes.
