摘要： Apparatus is provided including an external device including, a mount, which is placed in front of an eye of a subject. A power source is coupled to the mount and emits energy toward the eye. An intraocular device is implanted entirely in the subject's eye, and includes a control unit, a plurality of stimulating electrodes, and an energy receiver, which receives the energy from the power source and generates a voltage drop in response thereto. A plurality of photosensors detect photons and generate a signal in response thereto. Driving circuitry is coupled to the energy receiver and to the photosensors, and drives the electrodes to apply electrical charges to a retina in response to the signals from the photosensors. The external device modulates the emitted energy, and the control unit demodulates the modulated energy to regulate an operation parameter of the intraocular device. Other embodiments are also described.

摘要： A method and apparatus for implementing a CMOS buffer for driving a reference voltage that consumes very low current in normal operating conditions but drive high current when output voltage is off, tracking the required reference voltage. The circuit is operating in a “deadzone” most of the time, where pull-up and pull-down current paths are blocked, and ultra-low power comparators, with build-in offset, are monitoring the output voltage continuously, and driving compensation current, when needed. The circuit can be manufactured with a standard CMOS processing technology.

摘要： A substrate bias generator of the type that includes a driver for providing an AC signal to a charge pump node, a first switch coupled between the charge pump node and ground such that charge is pumped from the charge pump node to ground when the voltage at the charge pump node is near its peak, and a second switch coupled between the charge pump node and the substrate such that charge is pumped to the charge pump node from the substrate when the voltage at the charge pump node is near its most negative value. A unidirectional switch is provided between the first switch and ground to prevent charge from flowing from ground to the charge pump node when the second switch is open.
