Abstract
A disclosed method includes: setting a connector of an acquisition circuit and an associated capacitor to a predetermined potential; providing an energy pulse of a predetermined first time duration to the connector; at a time occurring substantially at a predetermined second time duration after an end of the predetermined first time duration of the energy pulse, coupling the associated capacitor and the connector of the acquisition circuit; and sampling a voltage being exhibited across the associated capacitor.
Claims24
An apparatus, comprising:
- a connector to couple to an electrode;
- a capacitor;
- a control circuit;
- a switching circuit responsive to the control circuit to:
- charge, or discharge, the connector and the capacitor to a predetermined potential;
- provide an energy pulse of a predetermined first time duration to the connector;
- and
- after an end of the predetermined first time duration of the energy pulse, couple the capacitor and the connector for a predetermined second time duration;
- and
- a sampling circuit to sample a voltage exhibited across the capacitor.
