摘要： This disclosure relates to methods, devices, and systems for delivering and adjusting stimulation therapy. In one example, a method comprising delivering, by a stimulation electrode, electrical stimulation as a candidate therapy to a patient according to a set of candidate therapy parameters, the stimulation electrode located in proximity to the dorsal column of a patient; sensing, by a sensing electrode, an electrically evoked compound action potential (eECAP) signal in response to the delivery of the electrical stimulation; and classifying, by a processor, the sensed eECAP signal generated in response to the application of the candidate therapy relative to an eECAP baseline is disclosed.

摘要： This disclosure describes a chopper stabilized instrumentation amplifier. The amplifier is configured to achieve stable measurements at low frequency with very low power consumption. The instrumentation amplifier uses a diffe rential architecture and a mixer amplifier to substantially eliminate noise and offset from an output signal produced by the amplifier. Dynamic limitati ons, i.e., glitching, that result from chopper stabilization at low power ar e substantially eliminated through a combination of chopping at low impedanc e nodes within the mixer amplifier and feedback. The signal path of the ampl ifier operates as a continuous time system, providing minimal aliasing of no ise or external signals entering the signal pathway at the chop frequency or its harmonics. The amplifier can be used in a low power system, such as an implantable medical device, to provide a stable, low-noise output signal.

摘要： This disclosure describes a capacitive interface circuit for a low power system. The capacitive interface circuit is configured to achieve very low n oise sensing of capacitance-based transducers, such as a micro-electro-mecha nical system (MEMS)-based sensor, with high resolution and low power. The ca pacitive interface circuit uses a differential amplifier and correlated trip le sampling (CTS) to substantially eliminate, or at least reduce, kT/C noise , as well as amplifier offset and flicker (1/f) noise, from the output of th e amplifier. The capacitive interface circuit may further include an output stage that reduces glitching, i.e., clock transients, in the output signal b y allowing transients in the amplifier output to settle. In this manner, the circuit can be used in a low power system to produce a stable, low-noise ou tput.
