Abstract:

Q-Dot, Inc. proposes an innovative "no-drop" regulator (NDR) for low-voltage micro-power sensor systems. Based upon charge-coupled devices (CCD's), it provides high efficiency with less noise and at a low cost. Designed for battery or solar-cell systems, it has zero-volt input-to-output differential for highly efficient "no-drop" regulation. A 3 V NDR requires only two 1.5 V batteries, decreasing its size and weight. A linear regulator's inherent diode drop requires three batteries. A switch-mode regulator includes an isolation diode, reducing its efficiency and limiting the maximum input voltage to a diode drop above the desired output voltage. The NDR provides isolation without a diode, allowing operation with higher voltages. CCD's also produce lower noise and ripple than conventional switch-mode regulators. Voltage multiplication is possible with the NDR if desired. Thus, more efficient, lower-noise operation over a wider voltage range than competing regulators is possible. The NDR feasibility will be assessed during Phase I. Prototypes will be fabricated and tested during Phase II. Broad DARPA and commercial applications will drive Phase III production of this innovative regulator concept. ANTICIPATED BENEFITS: High-efficiency regulation will extend the life of any battery-operated system. Examples include hand-held telecommunication, GPS, and imaging systems; notebook and laptop computers; cellular phones and mobile radios; remote sensors and data collection systems; pagers, beepers, and other remote signalling devices.
