    摘要： Devices and methods provide for the sensing of physiological signals during stimulation therapy by preventing stimulation waveform artifacts from being passed through to the amplification of the sensed physiological signal. Thus, the amplifiers are not adversely affected by the stimulation waveform and can provide for successful sensing of physiological signals between stimulation waveform pulses. A blanking switch may be used to blank the stimulation waveform artifacts where the blanking switch is operated in a manner synchronized with the stimulation waveform so that conduction in the sensing path is blocked during the stimulation pulse as well as during other troublesome artifacts such as a peak of a recharge pulse. A limiter may be used to limit the amplitude of the sensed signal, and hence the stimulation artifacts, that are passed to the amplifier without any synchronization of the limiter to the stimulation waveform.

    摘要： A device for sensing a physiological signal while stimulation therapy is being provided wherein the stimulation therapy involves application of a stimulation signal comprising a stimulation phase and a passive or active recharge phase, comprising: a sensing electrode; a blanking switch; an electrically conductive pathway connected between the sensing electrode and a blanking switch; a sensing amplifier; a controller configured to maintain the blanking switch in a non-conducting state during a stimulation phase of a stimulation signal and to maintain the blanking switch in a conducting state during at least a portion of the recharge phase.
