Triple wavelength LED driver for optical brain–computer interfaces
A dedicated triple wavelength LED driver is presented for optical brain–computer interfacing (BCI). The solution caters for the constraints of a common-anode grounded case and modulation up to several kilohertz that allows source separation of light that has backscattered from the brain. With total harmonic distortion of 0.95% and a frequency range of 40 kHz, the driver has application in a con...
متن کاملLED Driver Lifetime and Reliability
While LEDs themselves are extremely reliable and have a long lifetime, are electronic LED drivers capable of providing the required current/voltage input to the LEDs over their whole lifetime? This paper aims to address the above question in general and for the Xitanium family of LED drivers developed by Philips Lighting specifically. It will describe some of the strategies which Philips applie...
متن کاملIntegrated optical driver for interferometric optical gyroscopes.
We present the first chip-scale "integrated optical driver" (IOD) that can interrogate with a sensing coil to realize an interferometric optical gyroscope. The chip comprises a light source, three photodiodes, two phase modulators and two 3-dB couplers within an area of 4.5 mm2. This allows for a significant reduction in size, weight, power consumption and cost of optical gyroscopes.
متن کاملOverstress-Free Charge Pump White LED Driver
This paper presented a white light emitting diode (LED) driver that utilized charge pump in boosting the input voltage. The output voltage had been made sure that it was sufficient enough to overcome the forward voltage of the LED as well as provide voltage headroom for the transistors in every LED channel branch. The charge pump and its peripheral circuit, the clock booster circuit, do not suf...
متن کاملMultiple Wavelength LED on Monolithic QW Structure
A monolithically integrated multi-wavelength LED based on selective dielectric cap intermixing is investigated experimentally. The proposed LED emits radiation with multiple wavelength peaks from one compact easy to fabricate quantum well (QW) structure. Each wavelength has an independent emission power control, allowing the LED to radiate one or more wavelengths simultaneously. The LED materia...
