  • Publication number: 20140266101
    Abstract: A programmable linear voltage regulator and system for programming the regulator that improves the speed, power usage, and stability over conventional linear voltage regulators is disclosed. A controller that has knowledge of the current or expected activation of various loads sends bias control signals to a programmable biasing circuit of an error amplifier in the voltage regulator to adjust the bias current in accordance with the load current the regulator produces or is expected to produce. A look up table associated with the controller can be used to correlate the bias control signals with current or expected load conditions. Programming of the programmable biasing circuit may precede the enablement of a new load condition to ready the voltage regulator to handle the upcoming change in load current.

  • Publication number: 20130245723
    Abstract: A neurostimulation device capable of being placed between an active stimulation state and an inactive stimulation state and method of using same. The neurostimulation device comprises a plurality of electrical terminals configured for being respectively coupled to a plurality of stimulation electrodes, a first solid-state switching device coupled to a first one of the electrical terminals, a variable power source coupled to the first switching device, and a controller configured for, when the neurostimulation device is in the inactive stimulation state, prompting the variable power source to selectively output a relatively low voltage to place the first switching device into a first open state and a relatively high voltage to place the first switching device into a second open state.
