    摘要： This disclosure describes techniques for generating stimulation current pulses that have differing pulse shapes in a medical device. A circuit architecture is described that is configured to charge a capacitor to an initial amount of charge, modulate the amount of charge stored in the capacitor based on a control signal, and generate a stimulation current pulse that has an amplitude based on the amount charge stored in the capacitor. The circuit architecture may be configured to generate complex pulse shapes, such as, e.g., steps, ramps, bursts, and combinations thereof.

    摘要： A flux-gate magnetometer having a drive signal for reducing the effects of electromagnetic interference (EMI) is provided. The drive signal has a characteristic that varies over time. For example, the drive signal may include a duty cycle that varies over time, the frequency of the drive signal may be varied over time, or the phase shift of the drive signal may vary over time.

    摘要： A system includes a capacitance adjustment module and a control module. The capacitance adjustment module is configured to connect one or more of N capacitors in parallel with one of a first and second capacitance. The control module identifies the smaller of the first and second capacitances and identifies the larger of the first and second capacitances. Subsequently, the control module, during each of M iterations, instructs the capacitance adjustment module to connect at least one of the N capacitors across a set of nodes in parallel with the smaller identified capacitance, and determines whether the capacitance associated with the set of nodes is greater than the larger identified capacitance. After the M iterations, the control module approximates the difference between the first and second capacitances based on which of the N capacitors are connected across the nodes. M and N are integers greater than or equal to 1.
