Abstract
Systems, devices, and techniques are described for calibrating a medical device that senses ECAP signals from a patient's nerve tissue. For example a method includes instructing, with processing circuitry, stimulation circuitry of a medical device to deliver, on stimulation electrodes of the medical device, an electrical stimulation signal having an amplitude substantially equal to zero to a patient, entering, with the processing circuitry subsequent to instructing the stimulation circuitry to deliver the electrical stimulation signal, a passive recharge state on stimulation electrode circuitry, and auto-zeroing, with the processing circuitry, inputs to an operational amplifier of sensing circuitry electrically coupled to sensing electrodes of the medical device while the stimulation electrode circuitry is in the passive recharge state.
