  • Publication number: 20200306543
    Abstract: Embodiments are directed to an implantable medical device comprising stimulation circuitry for controlling delivery of a medical therapy to a patient, a processor for controlling the IMD according to executable code, and a power source. The implantable medical device may further include current regulator circuitry comprising electrode selection circuitry that is configured to select electrodes for use during a discharge mode, and a programmable current regulator configured to provide an exponentially decreasing discharge current to the selected electrodes from the power source. A current output of a programmable current regulator may be decreased in precalculated steps to create the exponentially decreasing discharge current applied to the selected electrodes.

  • Publication number: 20050078841
    Abstract: A reset circuit apparatus is used with a buffer amplifier circuit to provide a low impedance shunt for improving the settling characteristics of buffer amplifiers, particularly as used with miniature electret microphones. The reset circuit comprises a detector and is coupled to a switch. The switch is activated when the detector is triggered by predetermined operating conditions. The switch activates a ramp generator for providing a delay signal of a predetermined period to a shunt or reset device coupled to the input of a buffer amplifier. A method for performing the reset function is also discussed and described.
