Abstract
Techniques, devices, and systems for isolating, by isolation circuitry connected to a power source, a voltage from the power source, receiving, by sensing circuitry, the isolated voltage, receiving, by the sensing circuitry, a reference voltage from an implantable reference electrode via a reference node, and sensing, by the sensing circuitry, the biomedical signal with two or more implantable sensing electrodes using the isolated voltage with respect to the reference voltage.
Claims16
A method comprising:
- isolating, by isolation circuitry connected to a power source, a voltage from the power source;
- receiving, by sensing circuitry, the isolated voltage from the isolation circuitry;
- receiving, by the sensing circuitry and via a reference node connected to a low power rail in the sensing circuitry, a reference voltage from an implantable reference electrode connected to the reference node;
- and
- sensing, by the sensing circuitry and via at least two or more implantable sensing electrodes, a biomedical signal of a patient using the isolated voltage with respect to the reference voltage.
